A polygon is a two-dimensional shape made of straight lines called sides. The sum of the interior angles in a polygon can be determined using the formula (n-2) x 180 degrees, where n is the number of sides. Polygons can be classified as regular or irregular based on the lengths and measures of their sides and angles.
In geometry, a polygon is a two-dimensional shape that is made up of straight lines called sides.
It is a closed figure with three or more sides. Examples of polygons include triangles, squares, pentagons, and hexagons.
In a polygon, the sum of the interior angles is determined by a formula: (n-2) x 180 degrees, where n is the number of sides.
For example, a triangle has 3 sides, so the sum of its interior angles is (3-2) x 180 = 180 degrees.
Polygons can be classified based on their sides and angles. Regular polygons have all sides and angles equal, while irregular polygons have sides and angles of different lengths and measures.
