Complete the following paragraph proof. (You may use the choices more than once and you may not use all the choices) FILL IN THE RESPONSE AREAS
Given: <5 and <7 are supplementary. <7 and <9 are also supplementary
Prove: <5 ≅
<9
(5 points)
We know that <5 and <7 are supplementary. <7 and <9 are also supplementary because it is Response aream<5 + m<7 = Response area and m< 7 + m<9 = Response area, by definition of supplementary angles. Then, m<5 + m<7 = m<7 + m<9 by the Response area. Subtract m<7 from each side and you get m<5 = m<9. Then by the definition of congruence, <5 ≅ Response area
answers: <7, 180 degrees, subtraction property, transitive property, given, 90 degrees, symmetric property, addition property, <9, <5, proven
