List the properties of quadrilaterals' midpoint quadrilaterals

Find the properties of the following quadrilaterals:
a. quadrilateral whose midpoint quadrilateral is a rhombus
b. quadrilateral whose midpoint quadrilateral is a square
c. quadrilateral whose midpoint quadrilateral is a rectangle

For example, all of the quadrilaterals from a ,b, and c have congruent diagonals.

Can you find more? Like anythings that relates to parallel bases, bisecting, angles, etc. Find as many as possible.

a. quadrilateral whose midpoint quadrilateral is a rhombus.
-------
Attn: You can easily prove it using the mid point segment is parallel to the base and equals to half of the base.
