Question

Draw a four-sided closed figure, in which:

(i) all the sides are equal and each angle is 90°.

(ii) opposite sides are equal and each angle is 90°.

Write the special name of each figure drawn.

Answer 1

(i) In this four sided closed figure all the sides are equal and each angle is 90°. This figure is called a square. In ABCD, AB = BC = CD = DA and ∠A = ∠B =∠C = ∠D = 90°

(ii) In this four sided closed figure opposite sides are equal and each angle is 90°. This figure is called a rectangle In rectangle ABCD, AB = CD and BC = AD ∠A = ∠B = ∠C = ∠D = 90°.
