WebOct 1, 2024 · A regular pentagon has five equal angles, which all measure 108 degrees. The side length is all equal as well. The sum of the interior angles of a regular pentagon is 540 … A pentagon is a closed two-dimensional polygon with 5 sides and 5 angles. Based on the properties, a pentagon can be classified into different types. They are: Regular Pentagon:A pentagon having all its sides and interior angles equal. Irregular Pentagon:All the sides of a pentagon are not equal and the … See more The sum of angles in a pentagon is the sum of five angles of the pentagon. Now let us discuss the sum of interior and exterior angles of a pentagon. See more The angles formed by two adjacent pairs of sides are called interior angles of a pentagon. Number of sides = Number of vertices = Number of interior angles = 5 Two interior angles … See more The measure of the central angle of a regular pentagon makes a circle, i.e. total measure is 360°. If we divide the pentagon into five congruent triangles, then the angle at one vertex of them will be 72° (360°/5 = 72°). See more Exterior angles of a pentagon are the angles formed outside the pentagon with its sides when the sides of the pentagon are extended. Each exterior angleof a pentagon is equal to … See more
