Interior Angles of Polygons
In geometry, an interior angle of a polygon is an angle formed by two adjacent sides of the polygon that lie on the same side of a straight line passing through the polygon’s vertices.
The sum of the interior angles of a polygon with nsides is given by the formula:
$$S = (n-2) \times 180^\circ$$
where Sis the sum of the interior angles and nis the number of sides.
Relationship between the Number of Sides and the Measure of Interior Angles
The number of sides of a polygon has a direct relationship with the measure of its interior angles. As the number of sides increases, the measure of each interior angle decreases. This is because the total sum of the interior angles remains constant, but it is distributed among a greater number of angles.
Exterior Angles of Polygons: Interior And Exterior Angles Of Polygons Worksheet With Answers Pdf
Exterior angles of polygons are angles formed by one side of a polygon and the extension of an adjacent side. They are measured in degrees and can be used to find the sum of the interior angles of a polygon.
To measure an exterior angle, extend one side of the polygon and measure the angle between the extended side and the adjacent side. The exterior angle is the angle that is not adjacent to the polygon.
Sum of Exterior Angles of Polygons
The sum of the exterior angles of a polygon is always 360 degrees. This is because the sum of the interior angles of a polygon is 180(n-2) degrees, where n is the number of sides of the polygon. The sum of the exterior angles of a polygon is 360 – 180(n-2) = 360 degrees.
Formula for the sum of exterior angles of a polygon: 360 degrees
