Quadrilateral That Is Not Regular – A rectangle is a flat figure consisting of four distances that close in space. The easiest and fastest way to learn about rectangles is to build them yourself.
Find four flat objects to use as line segments (four = rectangle; side = side). Anything will do, and they don’t have to be the same length: straws, rulers, dowels, pens — whatever you have on hand. If you connect four linear objects at their eight vertices, you have a quadrilateral, a four-sided polygon.
Quadrilateral That Is Not Regular
You may have placed four sides so that the shape looks perfect, meaning you have made a convex quadrilateral. Perhaps your four line segments created a pointed shape like an arrowhead; You have made a concave rectangle.

Usually the four sides do not intersect and form a simple square. You can arrange a quadrilateral so that its segments intersect: you have a complex quadrilateral.
A quadrilateral has 4 straight sides. The sides and angles can be equal or unequal. If two or four sides are equal, we get special types of quadrilaterals, such as trapezoids and rectangles.
Two sides of a quadrilateral can intersect – a compound quadrilateral – which makes the quadrilateral look like two adjacent triangles.
Use a ruler or ruler to draw a rectangle. Draw four line segments so that each endpoint touches another endpoint. Whether you’re building a simple or complex, convex or concave square, you’ve done it right!

Draw a simple rectangle. Do not allow line segments to cross. Your simple rectangle can be concave or convex. If the sides are facing inwards, you have drawn a concave quadrilateral.
Now draw a rectangle that intersects two non-adjacent segments. You have drawn a complex quadrilateral.
Each point is assigned a letter that moves in any direction (clockwise or counterclockwise) to the next point, like a square.
A simple square is also called a quadrilateral or quadrilateral. A regular quadrilateral is symmetrical if it has at least one pair of congruent sides.

All concave quadrilaterals have one of their diagonals outside the enclosure. All complex quadrilaterals have two diagonals outside the closed space.
You may have noticed that a complex quadrilateral has sides that intersect themselves. In mathematics, angles formed by intersections are not part of a shape.
A complex quadrilateral has two acute interior acute angles and two interior reflex angles. These two angles of the reflector look shapeless, which can be confusing. They are still considered “interior” angles.
A quadrilateral is said to have only four interior angles, even though two segments intersect to form two more interior angles. Lines that intersect themselves do not add two angles to a complex quadrilateral.
State Whether The Following Quadrilaterals Are Similar Or Not
In this lesson, you learned that a quadrilateral is a flat figure consisting of four sides that close in space. Special types of quadrilaterals, such as rectangles, trapezoids, and squares, have more limited definitions.

In geometry, a quadrilateral is a four-sided polygon with four edges (sides) and four corners (vertices). The word comes from the Latin quadri, quadri and latus, meaning “jaw”. It is also called a tetragon, from the Greek “tetra” meaning “four” and “gon” meaning “corner” or “corner”, similar to other polygons (such as the ptagon). Since “gon” means “corner”, it is similarly called a quadrangle or 4 corners. A quadrilateral with vertices A, B, C and D is sometimes denoted by a dot as ◻ A B C D.
Quadrilaterals are either simple (not self-intersecting) or complex (intersecting or intersecting). Simple rectangles are either convex or concave.
The interior angles of a simple (and planar) quadrilateral ABCD add up to 360 degrees of arc, i.e.
This is a special case of the formula for the sum of the interior angles of an n-gon: S = (n − 2) × 180°.
How To Calculate The Approximate Area Of Irregular Shapes Using Simpson’s 1/3 Rule
In a convex quadrilateral, all interior angles are less than 180° and both diagonals lie inside the quadrilateral.
In a concave quadrilateral, one interior angle is greater than 180°, and one of the two diagonals lies outside the quadrilateral.
A square that intersects itself is called a horizontal square, a cross square, a butterfly square, or an arc square. In a crossed quadrilateral, the four “interior” angles on either side of the intersection (two acute and two reflex, all to the left or all to the right when drawn) add up to 720°.
The two bimedians of a convex quadrilateral are the segments connecting the bisectors of the opposite sides.

They intersect at the “top” of the quadrilateral (see § Express Points and Lines in a Convex Quadrilateral below).
The four inflection points of a convex quadrilateral are perpendicular to one side through the center of the opposite side.
There are various heraldic formulas for the area K of a convex quadrilateral ABCD with sides a = AB, b = BC, c = CD, and d = DA.
In the case of an orthodiagonal quadrilateral (such as a rhombus, square, and kite), this formula reduces to K = p q 2 }} because θ is 90°.

Where the consecutive sides are a, b, c, d, where s is a semicircle, and A and C are two (in fact, any two) opposite angles. This leads to Brahmagupta’s formula for the area of a cyclic quadrilateral – which is A + C = 180°.
Another area formula for sides and angles, where angle C is between sides b and c, and A is between sides a and d:
In the case of a cyclic quadrilateral, the final formula is K = a d + b c 2 sin A. }sin.}
In a parallelogram with equal opposite sides and angles, this formula reduces to K = a b ⋅ sin A. .}

Another option is to write the surface in terms of the diagonal angle θ of the intersection and the sides, since the length θ is not 90°:
Here, x is the distance between the midpoints of the diagonals, and φ is the angle between the bimedians.
The final formula for a trigonometric surface including sides a, b, c, d and angle α (between a and b) is:
It can also be used for the area of a concave quadrilateral (the light part is opposite the angle α), simply by changing the first + sign to .

The following two formulas express the area in terms of sides a, b, c and d, hemispheres s and diagonals p, q:

The first leads to Brahmagupta’s formula in the case of a cyclic quadrilateral, since th pq = ac + bd.
