Question

6.) which definition/property/postulate 2 points justifies this step? 1.) <1 & <3 are complementary. given 2.) m<1+m<3=90 ____________ this is an illegal operation, youre going to need a lawyer definition of complementary angles addition property of equality congruent complements theorem 7.) if ∠1 and ∠2 are a linear pair, which 2 points of the following statement is not true? ∠1+∠2=180 ∠1 and ∠2 are supplementary ∠1 + ∠2 = 90 ∠1 and ∠2 are adjacent angles

Explanation:

For question 6, by the definition of complementary angles, if two angles are complementary, the sum of their measures is 90 degrees. For question 7, a linear - pair of angles are adjacent and supplementary, meaning the sum of their measures is 180 degrees, not 90 degrees.

Answer:

1. B. Definition of Complementary Angles
2. C. $\angle1+\angle2 = 90$
