What is the sum of the interior angles of a three-sided polygon?
The 3 interior angles of a 3 sided polygon which is a triangle add up to 180 degrees.
What is the angle sum for a 3 sided polygon?
The sum of the three INTERIOR angles is 180 degrees. And a 3-sided polygon is often referred to as a 'Triangle'.
What is sum of the interior angles of a polygon with three sides?
the sum of the interior angles of a 3 sided polygon is = 180 degrees. the sum of the interior angles of any polygon is given by 540/n. in this case n is = 3
What is the sum of the interior angles of a polygon with 18 sides?
For any N-sided polygon: Sum of the interior angles can be found by (N-2)*180°. Note that a 3 sided polygon (triangle) is the least number of sides possible. So for 18 sides: (18-2)*180° = 2880°
Does a 40 sided polygon have 6840 diagonals?
The sum of the angles of a regular n-sided polygon is equal to (n - 2) x 180 degrees.Therefore, the sum of the angles of a regular 40-sided polygon (tetradecagon) is equal to (40 - 2) x 180 = 6840 degrees. Therefore, 6840 refers to the sum of the degrees, not the number of diagonals.The number of diagonals of an n-sided polygon is given by n(n-3)/2. So a 40-sided polygon has 40*37/2=740 diagonals.
