A parellelogram has equal sides, the trapezoid is a parallelogram.
A parallelogram is a 4 sided quadrilateral.
No. Every rule that applies to a parallelogram applies to a rhombus, plus more.
No. They cannot be similar because a parallelogram has two pairs of sides with equal length. A parallelogram cannot have more than one pair.
No
If the system is truly forgotten then nobody will remember even one fact about it - leave alone a score or more!
Because a rectangle meets all the requirements of a parallelogram - and more.
A parallelogram can be considered as a slanted rectangle. More precisely, a parallelogram is a quadrilateral where each pair of opposite side is parallel.A parallelogram can be considered as a slanted rectangle.

I suggest you take a look at the Wikipedia article on "triangle", or at some similar source. I am sure you can find lots of interesting facts there.

I can get you started with one: Nobody who knows anything about it calls it "the pi of a circle". Pi is pi.
Although a rhombus is a parallelogram. not all parallelograms are rhombuses. A parallelogram is any shape with two or more pairs of parallel sides.
Technically, a rhombus is a parallelogram, but a parallelogram is not always a rhombus. A parallelogram is any four-sided shape with two sets of parallel lines. A rhombus is a parallelogram with all equivalent side lengths. So, a rhombus is a more specific parallelogram. (And so is a a square or a rectangle.)
