Question

prove that
1 triangle DCN is congruent to triangle BAM
2 triangle DAM is congruent to triangle BNC
3 DNBM is a parallelogram​

Answer 1

Step-by-step explanation:

DNBM is a parrallelogram

In triangle DCN and BAM

DN=MB(PARALLELOGRAM)

ANGLE A =ANGLE C ( ALTERNATE INTERIOR ANGLE)

BY AA CRITERIA ∆DCN ~∆BAM

IN SECOND CASE ALSO SAME LIKE THIS.
