Quadrilaterals
The Rectangle
-
A rectangle is a four-sided shape where every angle is a right angle (90°).
Also opposite sides are parallel and of equal length.
The Square
A square has equal sides (marked "s") and every angle is a right angle (90°)
Also opposite sides are parallel.
A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).
-
The Rhombus
-
A rhombus is a four-sided shape where all sides have equal length (marked "s").
Also opposite sides are parallel and opposite angles are equal.Another interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.
A rhombus is sometimes called a rhomb or a diamond.
The Parallelogram
-
A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "A" are the same, and angles "B" are the same).
-
The Kite
Each pair is made of two equal-length sides that join up.the angles where the two pairs meet are equal.
the diagonals, shown as dashed lines above, meet at a right angle.
one of the diagonals bisects (cuts equally in half) the other.
