Question

Give reasons for the following.
A square can be thought of as a special rectangle.

Answer 1

In a rectangle, all the interior angles are of the same measure, i.e., ${90}^o$ and only the opposite sides of the rectangle are of the same length whereas in case of a square, all the angles are of ${90}^o$ and all the sides are of the same length. In other words, a rectangle with all sides equal becomes a square. Therefore, a square is a special rectangle.
