All Shapes That Have 4 Sides – A geometric figure can be called a figure or area enclosed by a boundary formed by joining a certain number of curves, points and lines. There are different geometric shapes: Triangle, Circle, Square, etc. It is very important that you get the necessary understanding of geometric figures. For example; common geometric shapes such as square, rectangle, circle, triangle, etc. Here are some geometric shapes and definitions;

A square is a four-sided area connected by 4 line segments. Line segments in a square are all identical lines. Together they form 4 right angles.

If we talk about another geometric shape, the circle, it does not have straight lines. Instead, it’s a combination of spins that are all connected. There are no angles in a circle.

Like a square, a rectangle is formed by connecting four line segments. But the only difference is between a square and a rectangle. Additionally, a rectangle has two lines that are longer than the other two line segments. Therefore, in geometry, a rectangle is called a long square.

A triangle consists of three connected line segments. Unlike the squares in a triangle, the angles can have different sizes. It’s not always the right angle. A triangle is named after the type of angle it contains. For example, if a triangle has one right angle, it is called an isosceles triangle.

If all the angles of a triangle are less than 90 degrees, it is called an acute triangle. If any angle of a triangle is greater than 90 degrees, it is called an obtuse triangle. Finally, there is a right triangle where all the angles of the triangle are 60 degrees. On the other hand, triangles can be classified or labeled by the type of sides. Scalene triangles do not have congruent sides. An isosceles triangle has two sides. An equilateral triangle has three equal sides. A quadrilateral is a plane figure made of four lines closed in space. The easiest and fastest way to learn quadrilaterals is to make your own.

Find four straight objects to use as line segments (four = square; side = side). Anything will work, they don’t have to be the same length: straws, rulers, screws, pens – whatever you have on hand. If you connect four linear objects at their eight ends, you get a quadrilateral and a quadrilateral polygon.

Geometric Shapes Names

This means that you have created a quadrilateral, and the four sides may have been placed so that the shape appears complete. Perhaps your four-line section is shaped like an arrowhead; you have made a concave square.

It is usually a simple square with four sides not intersecting. You can arrange your quadrilateral so that line segments intersect: you have a complex quadrilateral.

A quadrilateral has 4 straight sides. Sides and angles may be equal or unequal. If two or four sides are equal, you get a special type of square, such as a trapezoid or rectangle.

Two sides of a quadrilateral can intersect to create a complex quadrilateral, making your quadrilateral look like two contiguous triangles.

Use a ruler or ruler to draw the rectangle. Draw four line segments so that each endpoint reaches a different endpoint. Whether you drew simple or complex, convex or concave squares, you did it right!

Draw a simple rectangle. Do not allow line segments to intersect. Your simple quadrilateral can be concave or convex. If both sides point inward, you have drawn a concave square.

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

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

A regular quadrilateral is also called a square or a tetragon. A regular quadrilateral is symmetrical if it has at least one pair of equal sides.

All concave quadrilaterals have one of their diagonals outside the closed space. All compound quadrilaterals have diagonals outside the closed space.

You may have noticed that complex quadrilaterals have self-intersecting sides. However, mathematically, the angle formed by the point of intersection is not part of the shape.

A complex quadrilateral has two interior acute angles and two interior reflex angles. The appearance of these two reflex angles can be confusing. They are still considered “inside corners”.

Although two line segments intersect to form two more interior angles, a quadrilateral is said to have only four interior angles. Line segments that intersect themselves do not add two angles to a compound quadrilateral.

In this lesson, you learned that a quadrilateral is a plane figure made up of four line segments closed in space. Certain types of quadrilaterals, such as rectangles, trapezoids, and squares, have more limited definitions.

A quadrilateral is a four-sided polygon with four corners. There are many types of quadrilaterals. The five most common types are parallelogram, rectangle, square, trapezoid, and rhombus.

A parallelogram is a quadrilateral with opposite sides parallel. But there are a number of tests to check if something is a parallelogram.

. Remember that each pair of opposite sides of a parallelogram has the same length. Glass,

A cube is an area of ​​space formed by six identical square faces connected at their edges. The three edges meet at each corner to form a vertex. A cube can be called a regular hexagon. It is one of the five regular manifolds known as Platonic solids.

A solid with two parallel faces whose cross-sections are congruent.

In any geometric solid consisting of planar surfaces (faces), an edge is a line segment where two such surfaces meet.

Two polygons are equal in size and shape, that is, if their corresponding angles and sides are equal.

Two figures of the same shape will be similar. If two figures are similar, then the ratio of the lengths of their corresponding sides is equal. Compare the corresponding sides to determine if the triangles below are similar.

What Shapes Have 4 Sides?

A polyhedron is a three-dimensional solid figure with each side having a flat surface. These flat surfaces are polygons and are connected at their edges. In geometry, a quadrilateral is a four-sided polygon with four edges (sides) and four angles (vertices). The word comes from quadri, a variant of 4, and the Latin word latus, meaning “side.” It is also called a tetragon from the words “tetra” meaning “four” and “gon” meaning “corner” or “angle” in comparison to other polygons (eg, Ptagon). Since “gon” means “angle”, it is similarly called a square or 4-gon. A quadrilateral with vertices A, B, C, and D is sometimes denoted ◻ A B C D .

Quadrilaterals are either simple (self-intersecting) or complex (self-intersecting or intersecting). Regular quadrilaterals are either convex or concave.

The interior angles of a simple (and flat) square ABCD are the sum of 360 degrees of the arc, i.e.

This is a special case of the formula for the sum of interior angles in n angles: S = (n – 2) × 180 °.

In a convex quadrilateral, all interior angles are less than 180° and both diagonals are inside the quadrilateral.

A concave quadrilateral has one interior angle greater than 180° and one of the two diagonals lies outside the quadrilateral.

Self-intersecting quadrilaterals are variously called transversal quadrilaterals, transverse quadrilaterals, butterfly quadrilaterals, and butterfly quadrilaterals. In a crossed quadrilateral, the four “interior angles” on either side of the intersection (two acute and two reflexes, all to the left or right if the figure is drawn) add up to 720°.

Two bimedias of a convex quadrilateral are line segments joining the midpoints of opposite sides.

Week #8 Assessment

They intersect at the “vertices” of the quadrilateral (see § Convex quadrilateral salient points and lines below).

The four diagonals of a convex quadrilateral are perpendicular to one side – passing through the midpoint of the opposite side.

There are several general formulas for the area K of a convex quadrilateral
