What is the sum of the angles in an N sided polygon?
What is the sum of the angles in an N sided polygon?
The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180.
What is the formula for n sided polygon?
The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with twelve sides, so we will let n = 12. The sum of the interior angles in this polygon would be 180(12 – 2) = 180(10) = 1800.
What is the formula for the sum of angles of a polygon?
S = ( n − 2) × 180° This is the angle sum of interior angles of a polygon.
What is the sum of the measures of the N straight angles?
Given an n-gon, you can always draw n-2 non-overlapping triangles within it (fix a vertex, connect it with two adjacent vertices). The sum of the interior angles in a triangle is 180, so the sum of all the interior angles is 180(n-2). There are n straight angles in the n-gon so there are 180n degrees total (part a).
What is the sum of the n interior angles?
The sum of the measures of the interior angles of an n-gon is sum = (n 2)180˚. .
What is the sum of exterior angles of a 25 Gon?
540.
What is the sum of the exterior angles of a regular 29 Gon?
The sum of the exterior angles of any polygon is always 360°.
What is the sum of the interior angles of a polygon that has 29 sides?
4860/29
What is the measure of each exterior angle of a regular 20 Gon?
So, for a regular 20-gon, each exterior angle is 360°/20 = 18°.
What is the measure of each exterior angle of a regular triangle?
An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees.
What is the measure of the regular triangle?
Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral.
What is the measure of an equiangular triangle?
A triangle whose all three sides and interior angles are equal is called an equiangular triangle. For a triangle to be equiangular, the measure of all its three interior angles must be equal to 60 degrees. An equiangular triangle has three equal sides, and it is similar to an equilateral triangle.
What does Equiangular mean in math?
more A triangle with all angles equal (they are all 60°) All sides are also equal. The same as an Equilateral Triangle.
What is another name for the equiangular triangle?

What is the other name for an equilateral triangular prism?
As a semiregular (or uniform) polyhedron A right triangular prism is semiregular or, more generally, a uniform polyhedron if the base faces are equilateral triangles, and the other three faces are squares.
