lines a and b are parallel. find the measure of ∠a. 116° a b m∠a = ?°
lines a and b are parallel. find the measure of ∠a. 116° a b m∠a = ?°
Answer
Explanation:
Step1: Identify angle - type relationship
When two parallel lines are cut by a transversal, corresponding angles are equal. $\angle a$ and the $116^{\circ}$ angle are corresponding angles.
Step2: Determine angle measure
Since corresponding angles are equal, $m\angle a=116^{\circ}$.
Answer:
$116$
