Question

lines a and b are parallel. find the measure of ∠a. 116° a b m∠a = ?°

Explanation:

Step1: Identify angle - type relationship

$\angle a$ and the $116^{\circ}$ angle are corresponding angles.

Step2: Apply property of corresponding angles

For parallel lines, corresponding angles are equal. So $m\angle a=116^{\circ}$.

Answer:

$116$
