vertex
A rectangle is a parallelogram in which all four vertex angles equal 90°.
8. (Its the corners)
A right angle triangle
if you did not know the answer would be a pentagon.
vertex
A rectangle minus a smaller rectangle which share a vertex.
It is called a diagonal and goes from any vertex to the next-but-one vertex.
A rectangle has FOUR vertices - at its corners. They are all equal to 90 degrees.

rectangle means same size and shape
You don't. A rectangle doesn't have a hypoteneuse, only a right-angled triangle has a hypoteneuse. As for the diagonal of a rectangle, you can draw it from any vertex to the opposite vertex. It's length is the square root of the sum of the squares of the longer and the shorter side-lengths.
