PART A. What would be the statement in step 4? m∠x + m∠y = m∠z + m∠y m∠x + m∠z = m∠z + m∠y m∠x + m∠y = m∠z + m∠x PART B. What would be thestatement in step 5? CHOOSE TWO THAT APPLY. CHOOSE ONLY ONE m∠x + m∠y = 180 m∠z + m∠y = 180 m∠x + m∠Z = 180 PART A. What would be the statement in step 4? m∠1 + m∠2 = m∠2 + m∠3 m∠1 + m∠3 = m∠2 + m∠1 m∠1 + m∠3 = m∠2 + m∠3 PART B. What would be thestatement in step 5? CHOOSE TWO THAT APPLY. CHOOSE ONLY ONE m∠1 + m∠2 = 180 m∠1 + m∠3 = 180 m∠2 + m∠3 = 180 a a a |
