Question

geometry basics constructing angles sam constructed ∠b as a copy of ∠a using a straightedge and compass. if the measure of ∠a is 42 degrees, what is the measure of ∠b? (1 point) the measure of the copy of the angle that sam created is ____ degrees. remaining attempts: 3

Explanation:

Step1: Recall angle copying property

When an angle is copied using a straightedge and compass, the measure of the copied angle is equal to the original angle.

Step2: Apply the property to ∠A and ∠B

Given \( m\angle A = 42^\circ \), and \( \angle B \) is a copy of \( \angle A \), so \( m\angle B = m\angle A \).

Answer:

42
