Hello from MrBillDoesMath!
Answer:
See Discussion section below
Discussion:
We know that
m<1 = m<2 ("measure" of angle 1 = measure of angle 2)
and
m<3 = m< 4
Adding these two equations gives
m<1 + m<3 = m<2 + m<4
From the diagram, m<1 + m<3 = m<CWE and m<2+m<4= m<FZH. Substituting these in the above equation gives:
m<CWE = m<FZH
