Question

Complete the two-column proof.

Given: <2 ≅ <4, M<2=110°
Proof: m<3 = 70°

m∠2 = m∠4 - Definition of congruent angles
m∠4 = 110º - b. ________
∠3 and ∠4 are a linear pair - Definition of a linear pair
∠3 and ∠4 are supplementary - Linear Pair postulate
m∠3 + m∠4 = 180º - c. _______
m∠3 = 70º - d. ________
