Question

Mary clams that you can cut a parallelogram along its diagonal and get two pieces that are the same size and shape Larry says that you can't cut all parallelograms this way who is correct explain you're thinking

Answer 1

No this isn’t always the case. For example, a kite is a parallelogram, but if you cut it in half horizontally, both pieces wouldn’t be the same

Answer 2

If any parallelogram is cut along one of the diagonals, we get 2 congruent triangles. We can see that the sides of the triangles are equal. Figure attached.

So, Mary is right.
