Quadrilateral Shapes And Their Names – In geometry, a quadrilateral is a closed shape formed by joining four points where the three points are non-collinear. A quadrilateral has 4 sides, 4 angles, and 4 vertices. ‘Quadrilateral’ is a word of Latin origin, ‘Quadra’ meaning four and ‘Latus’ meaning side. All four sides of a rectangle may or may not be equal.

A quadrilateral is a polygon with 4 sides, 4 angles and 4 vertices. When naming a quadrilateral, keep the order of the vertices in mind. For example, the following quadrilateral should be named ABCD, BCDA, ADCB, or DCBA. It cannot be named ACBD or DBAC because it changes the order of the vertices that form the quadrilateral. The following quadrilateral ABCD has four sides (AB, BC, CD, DA) and two diagonals (AC and BD).

Quadrilateral Shapes And Their Names

A quadrilateral always has 4 sides, 4 angles, and 4 vertices, but the sides and angles are different. It should be noted that the sum of the interior angles of a quadrilateral is always 360 °. The table below lists the different types of quadrilaterals.

Each quadrilateral discussed above has unique properties. However, there are some properties common to all quadrilaterals. It looks like this:

We will study other properties of other quadrilaterals in detail. You can identify a rectangle using the following properties:

A rectangle is a quadrilateral with two pairs of equal and parallel sides and four right angles.

There is nothing special about the sides, angles or diagonals of a trapezoid. However, if the lengths of two non-parallel sides are equal, it is called an isosceles trapezoid. The following quadrilateral XYZW is an isosceles trapezium with equal legs WX = ZY and equal diagonals XZ = WY.

Box area is the number of unit boxes that can fit inside. The table below presents the formula for the area of ​​a quadrilateral.

A quadrilateral is a closed two-dimensional figure with four sides, four angles, and four vertices. Some examples of quadrilaterals are squares, rectangles, and trapezoids.

There are different types of quadrilaterals identified according to their unique properties. For example, squares, rectangles, parallelograms, rhombuses, kites, trapezoids, and isosceles trapezoids are all classified as quadrilaterals.

Properties Of Quadrilaterals

In any type of quadrilateral, the sum of the interior angles is always 360°. For example, a rectangle is a quadrilateral with each interior angle 90°, so (90 × 4) = 360°.

Although there are many different types of quadrilaterals, they share some common properties. They are listed as:

Area is the space enclosed by any shape. A rectangle is a shape with four sides, and the area occupied by the rectangle is called its area. Some examples of rectangles are squares and rectangles. The area of ​​the square on the ‘a’ side is calculated by the formula: area = ‘a × a’ or a

The area of ​​the rectangle ‘l’ and the width ‘w’ are calculated using the formula area = ‘l × b’. The area of ​​a rectangle is always expressed in square units.

Perimeter is the length of the perimeter of any shape. Since we know that a square has four sides, the perimeter of the square can be found by adding all the sides of the square. For example, if a rectangle is 6 units long and 4 units wide, the formula for the perimeter of the rectangle is 2 (length + width). Substitute the value in the formula: 2 (6 + 4) = 20 units. Determine the shape using properties such as the number of sides, the number of angles, whether the shape is orthogonal, and whether the sides are the same length. Straight side. (Note – students do not need to identify acute and obtuse angles in shape. Nor do they need to use parallel or perpendicular language).

The answer is YES! Depending on the registered property, a rectangle can have more than one name. Sometimes we use the most common name to identify shapes, but students need to understand that names can be defined in many ways.

We need students to understand that shapes from different categories can share properties. Example: A lozenge and a rectangle show the properties of four faces.

Example: Because lozenges and rectangles share the properties of four sides in the quadrilateral category.

Different Types Of Shapes And Their Names (with Pictures)

We want to encourage students to use the defined attributes to justify why any name is given. Explanation of the example above.

“We know that a square can also be called a rectangle because a square must have two sets of equal sides and four right angles to be a rectangle. A square shows this property, so a square can be called a rectangle. A rectangle is not a square because it is a rectangle, four sides must be equal, and rectangles are not.”

As students learn how to name shapes, create a baseline chart that they can refer to when discussing rectangles. Some examples are:

• Create a shape as shown below and have students list all the names of the shapes and explain whether they fit.

Types Of Quadrilaterals And Their Properties

• Uninstall! Justify your reasons. Make four shapes, ask students to remove one, then explain why you use the properties and compare them.

• concept cards – create by giving examples and non-examples of certain quadrilaterals. In examples and non-examples, students define definitions for topics. It can be used for any geometry vocabulary, including many types of quadrilaterals.

• The Power of Venn Diagrams and Polygons – Used to compare and contrast properties of polygons or quadrilaterals. Consider the following activities. Provide students with three-dimensional venn diagrams and attribute labels for polygons, quadrilaterals, and right angles. Have students divide the shape into parts and explain why they are put where they are. (Note – GCG has a copy of the paper.) A quadrilateral is a planar figure made of four line segments that close in space. The easiest and fastest way to learn about quadrilaterals is to make your own.

Find 4 straight objects to use as sections (4 = rectangle, side = side). Straws, rulers, dowels, pens, whatever you can use, and they don’t have to be the same. Connecting 4 linear objects at their 8 ends produces a quadrilateral, 4-sided polygon.

You may have arranged four sides to make the shape look complete. That means you have created a convex quadrilateral. The four segments may form a pointed shape like an arrow. It is made into a concave rectangle.

It usually forms a simple rectangle with four non-intersecting sides. You can arrange the quadrilaterals so that the line segments intersect each other. So it’s a complex quadrilateral.

A quadrilateral has 4 straight lines. Sides and angles may or may not be equal. If 2 or 4 sides are equal, you get special types of quadrilaterals such as trapezoids and rectangles.

Any two sides of a quadrilateral can intersect each other. This is a complex quadrilateral. The quadrilateral then looks like two adjacent triangles.

Quadrilateral: Formula, Types, Venn Diagram & Perimeter

Draw a rectangle using a straight line or ruler. Draw 4 sections so that each end point touches the other end point. Whether you’re drawing simple or complex quadrilaterals, convex or concave, you’ve done it right!

Draw a simple rectangle. Make sure no line segments cross. A simple quadrilateral can be concave or convex. A concave rectangle is drawn with both sides pointing inwards.

Now draw a rectangle where two non-adjacent line segments intersect. You have drawn a complex quadrilateral.

Each vertex is assigned a character that moves in the direction (clockwise or counterclockwise) to the next vertex, such as a quadrilateral.

Solved What Is The Most Descriptive Name Of Each

A simple rectangle is also called a rectangle or rectangle. A simple quadrilateral is symmetrical if it has at least one pair of congruent sides.

Every concave quadrilateral has one of its diagonals outside the closed space. All complex quadrilaterals have two diagonals outside the closed space.

You may have noticed that complex quadrilaterals have their own intersecting faces. However, in mathematics, the angle formed by the intersection point is not part of the shape.

A complex quadrilateral has two internal acute angles and two internal reflective angles. These two angles of reflection can be confusing because they appear outside the shape. This is still considered an “inside” angle.

Although two line segments appear to intersect to create two more interior angles, the quadrilateral still says only four interior angles. Line segments that intersect themselves do not add two angles to a complex quadrilateral.

In this lesson, you learned that a quadrilateral is a plane figure with four closed line segments.
