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.
To draw a net for a wedge, start by visualizing the wedge as a triangular prism. Begin with a rectangle representing the base of the wedge, and then add two congruent right triangles on each end of the rectangle to represent the slanted sides. Finally, ensure that the triangles are oriented correctly to form the wedge shape when the net is folded. This will create a flat layout that can be folded into the 3D form of the wedge.

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
No not normally only if the parallelogram is in the form of a rectangle will it then have congruent diagonals.
Sometimes as when the parallelogram is in the form of a rectangle then its diagonals are of equal lengths.
