Polygon Interior Angles Theorem

Polygon breaks down into poly many gon angled from greek.

Polygon interior angles theorem. Brian mclogan 23 565 views. I can find the sum of the interior angle measures of a polygon. Maybe your real question should be why don t we call a triangle a trigon 3 angled or a quadrilateral a quadrigon 4 angled like we do pentagon hexagon heptagon octagon nonagon and decagon.

In order to find the measure of a single interior angle of a regular polygon a polygon with sides of equal length and angles of equal measure with n sides we calculate the sum interior angles or n 2 180 and then divide that sum by the number of sides or n. Polygon interior angles sum theorem the sum of the measures of the interior angles of a convex polygon with n sides is n 2 180. Its interior angles add up to 3 180 540 and when it is regular all angles the same then each angle is 540 5 108 exercise.

The points on a perpendicular bisector are equidistant from the endpoints of the segment that they bisect. S n 2 180 here n represents the number of. Depends on the number of sides the sum of the interior angles of a polygon should be a constant value.

No matter if the polygon is regular or irregular convex or concave it will give some constant measurement depends on the number of polygon sides. The formula for the sum of the interior angles of a polygon the formula for calculating the sum of the interior angles of a polygon is the following. For example a square has four sides thus the interior angles add up to 360.

Make sure each triangle here adds up to 180 and check that the pentagon s interior angles add up to 540 the interior angles of a pentagon add up to 540. I can use the polygon angle sum t. Given a polygon solve for x and all of the interior angles using sum of interior angles duration.

I can find the measure of each interior angle of a polygon. When a transversal intersects two parallel lines each pair of alternate interior angles are equal. The angles that lie inside a shape generally a polygon are said to be interior angles.
