Question

Given: m∠A + m∠B = m∠B + m∠C Prove: m∠C = m∠A Write a paragraph proof to prove the statement.

Answer 1

Answer:

Because both <A and <C equal the same amount (<B), we know that <A = <C.

Answer 2

Since angle a + angle b = angle b + angle c, subtract b from both sides cancelling them and now you are left with angle a = angle c
