What is the sum of the interior angles of the following polygon?
Theorem 39: If a convex polygon has n sides, then its interior angle sum is given by the following equation: S = ( n −2) × 180°.
Which is correct formula for sum of interior angles of a n sides of a polygon?
Interior Angles Theorem In a polygon of ‘n’ sides, the sum of the interior angles is equal to (2n – 4) × 90°.
What is the formula of the sum of interior angles?
The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

720°
Hexagon/Sum of interior angles
What do same side interior angles look like?
The same side interior angles formed when two parallel lines intersected by a transversal. The same side interior angles can be congruent only when each angle is equal to a 90 degree because then the sum of the same side interior angles is equal to 180 degrees.
What is the sum of the interior angles of a 21 sided polygon?
3240 degrees
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.
What is the sum of all three interior angles of a triangle?
The sum of the three angles of any triangle is equal to 180 degrees.
What is the sum of the interior angles of?
The sum of the interior angles is (n–2) × 180° for n sides; the sum of the exterior angles is 360°. A regular polygon has all its sides and angles equal.
What is the exterior angle of a polygon?
Exterior angle: An exterior angle of a polygon is an angle outside the polygon formed by one of its sides and the extension of an adjacent side. Interior and exterior angle formulas: The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180.
What is an interior polygon?
An interior angle of a polygon is an angle whose vertex is a vertex of the polygon, whose measure is equal to the smallest positive measure that describes a rotation from one side through the interior of the polygon to the other side.
What is a 12 sided polygon called?
Dodecagon: It is a twelve-sided polygon and is also called as 12-gon. All the sides and interior angles are of equal length with the measurement equal to 150 degrees and the measurement of the center angle is equal to 360 degrees. Use this online area of a dodecagon calculator to simplify your 12-gon area calculation work.
