Question

1. a section of a leaded glass window is shown below. given: - each piece of lead in the glass is a straight line segment. - ∠1 ≅ ∠2 - ∠1 ≅ ∠3 which justification proves that ∠2 ≅ ∠3? a. addition property b. transitive property c. vertical angles are congruent d. alternate interior angles are congruent

Explanation:

The transitive property states that if \(a = b\) and \(a = c\), then \(b = c\). Here, since \(\angle1\cong\angle2\) and \(\angle1\cong\angle3\), by the transitive property of congruence, \(\angle2\cong\angle3\).

Answer:

B. transitive property
