a squished rectangle
Correct
A parallelogram is anything from a square to a rectangle. As long as it has parallel sides, then it is a parallelogram. If you're thinking of a rhombus, then it has diagonal sides.
A parallelogram has two diagonals the same as all 4 sided quadrilaterals
True
There are lot of shapes in geometry. It is called polygons. Triangle, trapezoid, circle, parallelogram, rhombus, rectangle, diagonal, square etc. Parallelogram, rhombus, rectangle, diagonal, square, and trapezoid are quadrilaterals.
True.
Correct
you can't, because the Pythagorean theorem is for right triangles and the triangles formed by the diagonal of a parallelogram are not right triangles.
Suppose that the parallelogram is a rhombus (a parallelogram with equal sides). If we draw the diagonals, isosceles triangles are formed (where the median is also an angle bisector and perpendicular to the base). Since the diagonals of a parallelogram bisect each other, and the diagonals don't bisect the vertex angles where they are drawn, then the parallelogram is not a rhombus.

No. Most do not.
If you know the answer please tell me.
If you draw a diagonal line from corner to corner of a parallelogram, that is a line of symmetry.
Either diagonal of a parallelogram divides the parallelogram into two triangles of equal areas. Thus area of triangle abd = half that of the parallelogram abcd. The required ratio is 1 / 2.
Do exactly the same thing for a rhombus or a parallelogram A = base x height (parallelogram) OR A = 1/2 x diagonal 1 x diagonal 2
