Interior Angle
An interior angle is a geometric concept that refers to the angle formed by two adjacent sides of a polygon. It is the angle between two sides of a polygon that share a common vertex, or point of intersection, that lies within the polygon. The interior angle is measured in degrees and is always less than 180 degrees. In a regular polygon, all interior angles are equal, while in an irregular polygon, the interior angles can vary in size. The sum of the interior angles of a polygon is given by the formula (n-2) x 180, where n is the number of sides of the polygon. For example, a triangle has three sides, so the sum of its interior angles is (3-2) x 180 = 180 degrees. A quadrilateral has four sides, so the sum of its interior angles is (4-2) x 180 = 360 degrees. Interior angles are important in geometry because they help to determine the shape and properties of a polygon. For example, a polygon with all interior angles less than 90 degrees is called a convex polygon, while a polygon with at least one interior angle greater than 90 degrees is called a concave polygon. The number of sides and interior angles of a polygon can also be used to classify it as a triangle, quadrilateral, pentagon, hexagon, and so on. In summary, an interior angle is an angle formed by two adjacent sides of a polygon that lies within the polygon. It is measured in degrees and is always less than 180 degrees. The sum of the interior angles of a polygon can be calculated using the formula (n-2) x 180, where n is the number of sides of the polygon. Interior angles are important in determining the shape and properties of a polygon, and can be used to classify polygons based on their number of sides and interior angles.

Interior Angle
Interior angle is an angle formed by two adjacent sides of a polygon. It is the angle between two sides of a polygon that share a common vertex, or point of intersection. In a regular polygon, all interior angles are equal. The measure of an interior angle of a polygon is typically given in degrees. Interior angles can be classified into two categories: interior angles that are part of an inscribed polygon and interior angles that are part of an outer polygon. The formula for the interior angles of an inscribed polygon is based on the number of sides and the sum of the angles of the polygon. The formula for the interior angles of an outer polygon is based on the number of sides and the sum of the exterior angles of the polygon.
