Question

in the given figure, M is the mid-point of AB and CD. prove that CA || BD​

Answer 1

Step-by-step explanation:

In triangle CAM and DBM we have

AM=BM. .........(given)

CM=DM. .........(given)

angle CMA= angle DMB......(vertically opposite angles)

Therefore,the triangles are congruent

so angle CAM= angle MBD

hence CA II BD (alternate interior angles are equal)
