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.
There are 44 diagonals in an 11-sided polygon. heres how to find the amount of diagonals: S=amount of sides 1/2 S(S-3)
A 16 sided polygon has 104 diagonals
2. To find out how many diagonals are in a figure, just use this equation: n(n-3)/2 where n equals the number of sides therefore: 4(4-3)/2 4(1)/2 4/2 2 diagonals
