Question

first identify the types of angles in the figure. the exterior angle is ∠4. the non - adjacent interior angles are ∠1 and ∠2. what is the relationship between angles 3 and 4? m∠3 + m∠4 =

Explanation:

Step1: Recall linear - pair property

Angles 3 and 4 form a linear - pair.

Step2: Use linear - pair angle sum

The sum of angles in a linear - pair is 180 degrees. So, $m\angle3 + m\angle4=180^{\circ}$.

Answer:

180
