all regular polygons (such as a pentagon) have the sum of their exterior angles = 360 degrees
The sum of the exterior angles of all polygons equals to 360⁰.Since only the sum of the interior angles of all quadrilaterals equals to 360⁰, the polygon must have 4 sides.
As for all polygons the exterior angles add up to 360 degrees
All exterior angles of any polygon sum to 360 deg. If there are 9 angles then each angle is 40 degrees.
You are supposed to use the fact that the sum of all three angles is 180°.
The sum of all the interior angles of a triangle is 180 degrees while the sum of the exterior angles is 360. you can calculate for the measurements of the interior angles of a polygon by using the formula S=(n-2)(180) where n is the number of sides
The 3 interior angles of any triangle add up to 180 degrees and the 3 exterior angles add up to 360 degrees
Sum of interior angles - 180 degree (each side 60 degree) Sum of exterior angles of a polygon - 360 degree
The sum of all of the angles of a triangle will ALWAYS be 180 degrees.
If you multiply 360 by the number of angles in the polygon and then subtract the sum of all the interior angles you will end up with the sum of all the exterior angles of the polygon.
all regular polygons (such as a pentagon) have the sum of their exterior angles = 360 degrees
360A triangle is a polygon with three sides and three angles. The sum of the interior angles of a polygon equals 180(n - 2), where n is the number of sides.180(3 - 2) = 180°Assuming all the angles in the triangle are congruent, find the measure of one interior angle.180° ÷ 3 = 60°If an interior angle equals 60°, then its corresponding exterior angle will equal 120° because the angles are supplementary (their sum is 180°).120° × 3 = 360°Therefore, the sum of the exterior angles of a triangle is 360°.study island
-- The sum of the four exterior angles is 360 degrees. -- The sum of the four interior angles is also 360 degrees. -- So the sum of all the interior and exterior angles is 720 degrees.
The sum of the exterior angles of any regular polygon is 360°
The sum of the exterior angles of all polygons is 360 degrees.
Each pair of exterior and interior angles sum to 180 degrees.The sum of all exterior angles of a polygon is 360 degrees.
No way. All polygons have the same sum of exterior angles.You need the sum of interior angles.
