In Fig. 5.39, P, Q and R are collinear points and TQ ⊥ PR, Name the pair of complementary angles
Solution:
Given, P, Q and R are collinear points
Also, TQ ⊥ PR
We have to find the pair of complementary angles.
When the sum of the measures of two angles is 90°, the angles are called complementary angles.
From the figure,
Since TQ ⊥ PR,
We observe that ∠RQT is a right angle which measures exactly 90 degrees.
So, ∠RQT = ∠TQS + ∠RQS
Therefore, the pair of complementary angles are ∠TQS and ∠RQS.
