Question

if angle 1 in the picture is 63°, what is the measure of angle 3? why? (1 point)

Explanation:

Step1: Recall vertical angles property

Vertical angles are equal. Angle 1 and angle 3 are vertical angles.

Step2: Determine angle 3 measure

Since angle 1 = \(63^{\circ}\) and angle 1 and angle 3 are vertical angles, angle 3 = \(63^{\circ}\).

Answer:

The measure of angle 3 is \(63^{\circ}\) because angle 1 and angle 3 are vertical angles (vertical angles are congruent).
