A Quadrilateral has four-sides, it is 2- Four sides (edges)
dimensional (a flat shape), closed (the Four vertices (corners)
lines join up), and has straight sides. Interior angles that add to 360
degrees

THE SQUARE
THE RECTANGLE

A square has equal sides and every
A rectangle is a four-sided shape where angle is a right angle (90°)
every angle is a right angle (90°). Also opposite sides are parallel.A square
Also opposite sides are parallel and of also fits the definition of a rectangle (all
equal length. angles are 90°), and a rhombus (all sides
are equal length).

THE RHOMBUS

A rhombus is a four-sided shape
THE where all sides have equal length.

PARALLELOGRAM Also opposite sides are parallel and
opposite angles are equal.
Another interesting thing is that the

Also opposite angles are equal.
In other words they "bisect" each

other at right angles.
Rhombuses are all Parallelograms!
A rhombus is sometimes called a
rhomb or a diamond.

THE TRAPEZOID

A trapezoid has a pair of opposite sides parallel.
And a trapezium is a quadrilateral with parallel sides: An
Isosceles trapezoid, as shown above, has left and right sides of
equal length that join to the base at equal angles.
