Answer:
Step-by-step explanation:
12). Pair of supplementary angles means sum of the measures of a pair angles = 180°
So the three pairs will be,
m∠JKP + m∠JKL = 180°
m∠JKL + m∠LKM = 180°
m∠PKN + m∠NKL = 180°
13). Since obtuse angles measure more than 90°,
Two obtuse angles from the given picture will be,
∠JKL and ∠PKM
14). Since obtuse angles measure more than 90°, their sum will be more than 180°.
Therefore, two obtuse angles can never be supplementary.
