Question

The diagram shows parallel lines cut by two transversal lines creating a triangle. Which statements are true? Check all that apply.

m∠A = 20°
∠B and the angle marked 60° are alternate exterior angles.
m∠C = 100° because it is a vertical angle to the angle marked 100°.
∠B and ∠C are supplementary angles.
m∠A + m∠B + m∠C = 180°

Answer 1

Answer:40 super easy

Step-by-step explanation:

The diagram shows parallel lines cut by two transversal lines creating a triangle. Which statements are true? Check all that apply.

m∠A = 20°

∠B and the angle marked 60° are alternate exterior angles.

m∠C = 100° because it is a vertical angle to the angle marked 100°.

∠B and ∠C are supplementary angles.

m∠A + m∠B + m∠C = 180°
