How many exterior angles does a pentagon have
WebThe Interior Angles of a Pentagon add up to 540° The General Rule Each time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total: So the general rule is: Sum of Interior Angles = ( n −2) × 180 ° Each Angle (of a Regular Polygon) = ( n −2) × 180 ° / n Perhaps an example will help: WebJan 11, 2024 · No matter the shape, a regular polygon can have its exterior angles add to no more than 360°. Think: to go around the shape, you make a complete circle: 360°. So, divide 360° by the dodecagon's twelve exterior angles. Each exterior angle is 30°. Dodecagon exterior angles That was the easy part. The interior angles of a dodecagon are a bit harder.
