Question

Four angles are formed by the intersection of these lines. Choose the three true statements.

Answer 1

1. m∠1 = 60° because angle ∠1 and the 60° angle are vertical angles

2. ∠1 and ∠2 are adjacent.

3. m∠2 = 180° - 60°

Explanation:

m∠2 is not equal to 60° because it is the complementary angle of the one labeled 60°. Therefore, m∠2 = 30°. m∠2 can be determined by the information given. m∠1 ≠ m∠2 because m∠1 = 60° and m∠2 = 30°
