What is the sum of interior angle of a regular polygon if it has 14 diagonals?
900°
It has 14 diagonals. The sum of all interior angles is 900°. The sum of the exterior angles is 360°. Regular heptagon has all seven sides of equal length.
How many sides has a diagonal?
As applied to a polygon, a diagonal is a line segment joining any two non-consecutive vertices. Therefore, a quadrilateral has two diagonals, joining opposite pairs of vertices….Polygons.
Sides | Diagonals |

How many diagonals are there in a polygon of 15 sides?
90 diagonals
Therefore, there are 90 diagonals in a 15 sided polygon.
Do regular polygons have equal sides?
A polygon is called regular if it has equal sides and angles. Thus, a regular triangle is an equilateral triangle, and a regular quadrilateral is a square.
How many diagonals does a regular polygon have?
Each vertex must have the same number of diagonals entering or leaving it. So the 14 diagonals must be shared equally. So, the number of vertices must be one of 1, 2 or 7. Since polygons do not come in the first two varieties and so it is a heptagon. Originally Answered: a regular polygon has 14 diagonals. how many sides does the polygon have?
How do you find the number of sides of a polygon?
For very large sided polygons you may simply see it written “n-gon”, where “n” is the number of sides. For example, a 44-sided polygon would be written as 44-gon. If you are given a picture of the polygon, you can simply count the number of sides. Plug the number of sides into the equation.
How many diagonals can you draw with 14 vertices?
From every vertex you can draw 14 – 3 = 11 diagonals. You can draw 14*11 = 154 diagonals, but you will have drawn each one twice. For a 2-dimensional polygon with N sides, the number of diagonals is N (N-3)/2. If N = 14, then the result is 77. Cheers! Hiring CS majors for internships and entry-level roles.

How many diagonals does a decagon have?
Decagon (10 sides): n(n-3)/2 = 10(10-3)/2 = 10*7/2 = 70/2 = 35 diagonals. Icosagon (20 sides): n(n-3)/2 = 20(20-3)/2 = 20*17/2 = 340/2 = 170 diagonals. 96-gon (96 sides): 96(96-3)/2 = 96*93/2 = 8928/2 = 4464 diagonals.
