A 4 sided quadrilateral has 2 diagonals.
A triangle has 3 sides and no diagonals
It has 4 interior angles that add up to 360 degrees and 2 diagonals that intersect each other at right angles.
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
1/2*(n2-3n) = diagonals when n equals number of sides.
A geometrical triangle has 3 sides but no diagonals.
A 4 sided quadrilateral has 2 diagonals.
A triangle has 3 sides and no diagonals
It has 4 interior angles that add up to 360 degrees and 2 diagonals that intersect each other at right angles.
1/2*(152-45) = 90 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
1/2*(n2-3n) = diagonals when n equals number of sides.
A square.

Circumscribing.
Such at figure - as described - could not be made as a solid geometric shape.
A polygon with n sides has n*(n-3)/2 diagonals. Simple as that. So a 9 sided polygon has 9*6/2 = 27 diagonals.
