Question

To call any given shape a _____, the opposite sides of the shape must be equal, and all angles should be equal to $90°$.

• A. triangle
• B. circle
• C. trapezium
• D. rectangle

Answer 1

The correct option is D rectangle

To call any given shape a rectangle, the opposite sides of the shape must be equal, and all angles should be equal to ${90}^o$.

For example,


All the angles in the rectangle are 90°.
Side AB is parallel to side AC, and side AD is parallel to side BC.
Opposite sides are equal.
So, the figure is a rectangle.
Hence, option A is correct.
