If the diagonals are cong. then the figure is a rectangle.
Diagonals connect corners of a figure. If you try to connect two corners of a three sided figure, the lines you draw will exactly mimic the sides of the figure. Because of this, a three sided figure has no diagonals.
A 16 sided polygon has 104 diagonals
A 4 sided quadrilateral has 2 diagonals.

If the diagonals are cong. then the figure is a rectangle.
There are 170 diagonals
Diagonals connect corners of a figure. If you try to connect two corners of a three sided figure, the lines you draw will exactly mimic the sides of the figure. Because of this, a three sided figure has no diagonals.
A 16 sided polygon has 104 diagonals
0.5*(162-48) = 104 diagonals
0.5*(252-75) = 275 diagonals
A 4 sided quadrilateral has 2 diagonals.

no
1/2*(152-45) = 90 diagonals
The diagonals will not always bisect opposite angles in the rectangle.
