Question

List three ways a rectangle and a square are alike

Answer 1

They both have 4 sides. They both have all parallel sides. And they all have 4 corners

Answer 2

They are both quadrilaterals

With that fact we can come up with similarities:

Both have 2 pairs of parallel lines

Both have 4 right angles (Angles that measure 90°)

Both have 4 sides

Perimeters can be computed by adding all the sides.

Even if they are both quadrilaterals, they are not the same. A square has 4 equal sides. A rectangle is not a square, but a square is considered to be a special rectangle.
