Quadrilateral With Four Congruent Sides

Identifying Quadrilaterals

Today we will learn virtually what quadrilaterals are, quadrilateral shapes, types of quadrilateral etc. So let's beginning.

What are Quadrilaterals?

QUADRILATERALS are 2D shapes that are a type of polygon with 4 sides and 4 angles.
The sum of all interior angles of a quadrilateral is 360 degrees.

(QUAD means iv, LATERALS means side)

Types of Quadrilaterals

There are Vi basic types of quadrilaterals:

Parallelogram
Rectangle
Rhombus
Square
Trapezoid / Trapezium
Kite

What are polygons?

A polygon is a shape with AT LEAST 3 sides with NO curves and NO open sides.

What does parallel hateful?

Parallel means that lines go in the aforementioned direction and NEVER intersect/meet together.

What is a parallelogram?

Opposite sides are parallel and equal.
Reverse angles are equal.
Diagonals bifurcate each other.

What is a rectangle?

Opposite sides are parallel and equal.
All angles are 90º.
The diagonals bisect each other.

What is a rhombus?

All sides are equal and opposite sides are parallel.
Reverse angles are equal.
The diagonals bifurcate each other at right angles.

What is a square?

Opposite sides are parallel and all sides are equal.
All angles are 90º.
Diagonals bifurcate each other at right angles.

What is a trapezoid?

A trapezoid is a quadrilateral with EXACTLY One PAIR of parallel sides. Sides practise Not accept to exist equal in length.

Isosceles trapezoid: A trapezoid in which the nonparallel sides (the legs) are coinciding.

FUN FACT : Trapezoid defination are dissimilar for different people. Some people say that a trapezoid has AT Least ONE PAIR of parallel sides instead of EXACTLY One PAIR of parallel sides.

What is a kite?

Two pairs of adjacent sides are equal.
One pair of opposite angles is equal.
Diagonals intersect at correct angles.
The longest diagonal bisects the shortest diagonal into 2 equal parts.
