Question

prove with reason that in a parallelogram each diagonal divides it into congruent triangles​

Answer 1

Step-by-step explanation:

Since, both these triangles are congruent. So, all the corresponding sides and angles of one triangle are equal to that of the other. And AB = CD. Therefore, it is proved that the diagonal of a parallelogram divides it into two congruent triangles and also opposite sides of a parallelogram are equal.

Hope it helps you.....

Step-by-step explanation:

llgm means parallelogram.
