No not normally only if the parallelogram is in the form of a rectangle will it then have congruent diagonals.
Not always. You could form a kite. That means that the two adjacent sides would be congruent, not the two opposite sides.
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.

Parallelograms of any form, a square, a rectangle, and a rhombus are just special parallelograms so all will form 2 pairs of isosceles triangles when a diagonal is drawn.
Either 12,14,16,or18 I think 18. * * * * * The correct answers is 4. You can draw only 3 diagonals from one vertex.
If a parallelogram is in the form of a rectangle then both diagonals are congruent in lengths.
The three major diagonals in an ordinary hexagon do not intersect at the same point. Therefore, in such a hexagon, the diagonals form 111 triangles.
A square
Sometimes as when the parallelogram is in the form of a rectangle then its diagonals are of equal lengths.
No not normally only if the parallelogram is in the form of a rectangle will it then have congruent diagonals.
