Select all statements that could be the first step of an indirect proof of the conditional below.

If m∠4 = 95, then m∠3 = 85.
A. If m∠3 ≠ 85, then m∠4 ≠ 95.
B. If m∠4 = 95, then m∠3 = 85.
C. Assume if m∠3 ≠ 85, then m∠4 ≠ 95.
D. Assume if m∠4 ≠ 95, then m∠3 ≠ 85.
E. Assume if m∠4 = 90, then m∠3 = 85.
