WebA regular hexagon has 6 sides, so: Exterior Angle = 360 ° / 6 = 60° Interior Angle = 180 ° − 60° = 120° And now for some names: "Circumcircle, Incircle, Radius and Apothem ..." Sounds quite musical if you repeat it a few times, but they are just the names of the "outer" and "inner" circles (and each radius) that can be drawn on a polygon like this: WebJul 4, 2024 · What is heptagon shape? A heptagon is a seven-sided polygon. Regular heptagons have seven equal sides and seven equal angles. Why does a heptagon have 7 sides? A heptagon is a 7-sided polygon with 7 interior angles that sum to 900°. The name heptagon derives from the Greek words hepta- for seven and gon- for sides. datev auf windows 11
