Question

what true statement can you make about angle measures based on the diagram shown to the right? choose the correct answer below. m∠1 = 2·m∠2 ∠1≅∠2 m∠1 - m∠2 = 90° m∠1 + m∠2 = 180°

Explanation:

Step1: Identify angle - relationship

Angles ∠1 and ∠2 are a linear - pair of angles.

Step2: Recall linear - pair property

The sum of the measures of angles in a linear pair is 180°. So, \(m\angle1 + m\angle2=180^{\circ}\).

Answer:

\(m\angle1 + m\angle2 = 180^{\circ}\)
