Another one:
Row one is: 6 7 2 Row two is: 1 5 9 Row three is : 8 3 4 Even the diagonal is a sum of 15 : 6 5 4 and 2 5 8
[ 9 ] [ 2 ] [ 7 ][ 4 ] [ 6 ] [ 8 ][ 5 ] [10 ] [ 3 ]
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.
[ 9 ] [ 2 ] [ 7 ][ 4 ] [ 6 ] [ 8 ][ 5 ] [10 ] [ 3 ]
There are 170 diagonals
If the diagonals are cong. then the figure is a rectangle.

A 16 sided polygon has 104 diagonals
A 4 sided quadrilateral has 2 diagonals.
0.5*(252-75) = 275 diagonals
0.5*(162-48) = 104 diagonals
no
1/2*(152-45) = 90 diagonals
The diagonals will not always bisect opposite angles in the rectangle.
A four-sided figure whose diagonals are perpendicular is a kite. In a kite, two pairs of adjacent sides are equal, and the diagonals intersect at right angles. Additionally, one of the diagonals bisects the other, creating symmetry in the figure. Other quadrilaterals, like rhombuses, also have perpendicular diagonals, but a kite is specifically defined by its side lengths and angle properties.
