Question
Identify whether the pair of angles are complementary or supplementary: $80º, 10º$
✓
Answer
We know that two angles are complementary if their sum is $90^{\circ}$
Here, the Sum of the measures of the given pair of angles $=80^{\circ}+10^{\circ}=90^{\circ}$
As the sum of these angles is equal to $90^{\circ}$
Therefore, these angles are complementary angles.
