Identify the correct justification for each step, given that 2 and 3 are complementary, and m1=m3 . The figure shows four rays with a common endpoint B. Ray B A is directed to the upper left corner. Ray B D is directed vertically upward. Ray B E is directed to the upper right corner. Ray B C is directed horizontally to the right. Rays B A and B D form angle 1. Rays B D and B E form angle 2. Rays B E and B C form angle 3. 1. 2 and 3 are complementary 2. m2+m3=90 3. m1=m3 4. m1+m2=90 5. 1 and 2 are complementary
