4lines extend from point e. a horizontal line extends to the left to point a and a vertical line extends up to point c. another line extends halfway between the other 2 lines to point b. lines a e and e c form a right angle. given that ∠cea is a right angle and ray e b bisects ∠cea, which statement must be true? ∠bea ≅ ∠cea ∠ceb ≅ ∠cea m∠ceb = 45° m∠cea = 45°
