Number 1

Write a paragraph proof to prove that / 2 and / 3 are complementary given that / 1 and / 2 are complementary, and m/1 = m/3. A 2 O It is given that 21 and 42 are complementary. By the Additive Property of Equality, my1 + mz2 = 80%. It is given that my1 = my3. So, by the Substitution Property of Equality, m23 + mz2 = 80. Thus, by the definition of complementary angles, 22 and 23 are complementary. O It is given that 21 and 22 are complementary. By the definition of complementary angles, mc1 + my2 = 80*. It is given that my1 = m
