Question

pqrs is a parallelogram. is the midpoint of PQ and b is the midpoint of ASR. show that a cube is a parallelogram ​

Answer 1

Answer:

Looking at figure attached

Now we have sufficient condition to prove that MSQN is parallelogram so its opposite sides are parallel so MS || QN.

Step-by-step explanation:

MS is not parallel to QN
