1.	Identify which of the following pairs of angles are complementary and which are supplementary.(i) 130°, 50°(ii) 45°, 45°(iii) 80°, 10°
Answer» (i) 130° + 50° = 180° ∴ This pair is supplementary angles. (ii) 45° + 45° = 90° ∴ This pair is complementary angles. (iii) 80°+ 10° = 90° This pair is complementary angles.

Identify which of the following pairs of angles are complementary and which are supplementary.(i) 130°, 50°(ii) 45°, 45°(iii) 80°, 10°

Answer»

(i) 130° + 50° = 180°
∴ This pair is supplementary angles.

(ii) 45° + 45° = 90°

∴ This pair is complementary angles.

(iii) 80°+ 10° = 90°

This pair is complementary angles.
