1.	Identify which of the following pairs of angles are complementary and which are supplementary.(i) 65°, 115°(ii) 63°, 27°(iii) 112°, 68°
Answer» (i) 65° + 115° = 180° ∴ This pair is supplementary angles. (ii) 63°+ 27° = 90° ∴ This pair is complementary angles. (iii) 112°+68°= 1800 ∴ This pair is supplementary angles.

Identify which of the following pairs of angles are complementary and which are supplementary.(i) 65°, 115°(ii) 63°, 27°(iii) 112°, 68°

Answer»

(i) 65° + 115° = 180°

∴ This pair is supplementary angles.

(ii) 63°+ 27° = 90°

∴ This pair is complementary angles.

(iii) 112°+68°= 1800

∴ This pair is supplementary angles.
