Question

find m∠1, m∠2 and m∠3. explain your reasoning.

m∠1 =

m∠3 =

m∠2 =

80° 100° corresponding angles theorem
alternate exterior angles theorem

Explanation:

Answer:

\(m\angle1 = 80^{\circ}\) by the Corresponding Angles Theorem
\(m\angle3 = 80^{\circ}\) by the Alternate Exterior Angles Theorem
\(m\angle2 = 100^{\circ}\) by the Linear - Pair Postulate
