Q2 of 23 Page 22

Ray PQ and ray PR are perpendicular to each other. Points B and A are in the interior and exterior of ∠QPR respectively. Ray PB and ray PA are perpendicular to each other.

Draw a figure showing all these rays and write -


i. A pair of complementary angles


ii. A pair of supplementary angles.


iii. A pair of congruent angles.


iii. A pair of congruent angles.

The figure is attached below:



(i) ∠ RPB + ∠ BPQ = 90°


(ii) ∠ RPQ + ∠ BPA = 180°


(iii)∠ RPQ = ∠ BPA (congruent angle)


(iv) ∠ RPB = ∠ QPA (congruent angle)
