Question

Points A and B are on the same side of a line l . AM and BM are perpendicularls to the line l . If C is the mid point of AB prove that CM=CN

Answer 1

Answer:

Step-by-step explanation:

in ΔAMC and ΔBNC

AC=CB (C is the midpoint of AB)

∠MCA=∠NCB

∠A=∠B (90°)

∴ ΔAMC≅ΔBNC (ASA)

CM=CN (CPCT)
