Given that bisects ∠CEA, which statements must be true? Check all that apply. m∠CEA = 90° m∠CEF = m∠CEA + m∠BEF m∠CEB = 2 (m∠CEA) m∠BEF = 135° ∠CEF is a straight angle. ∠AEF is a right angle.

The statement that must be true is ∠AEF is a right angle. The right angle is exactly 90 degrees. Bisecting the angles resulted to a right triangle. This process is dividing the equal or same parts. The correct answer is the last statement or sentence.
