What does a rectangular look like?

Answer 1

A rectangle is a type of parallelogram (a four sided figure with two pairs of opposite parallel sides). In fact, a rectangle is an equiangular parallelogram, meaning all the angles are congruent. Using the polygon interior angle theorem, you can use simple math to find that all four angles in a rectangle equal 90 degrees (right angles). Also, the opposite sides of a rectangle are congruent.
