Web11 jan. 2024 · It has 12 straight sides enclosing a space It has 12 interior angles Sometime during the mid 1600s, a mathematician felt the need for a descriptive word for a 12-sided polygon. The word dodecagon comes from the Greek, dōdeka-, which means 12, and + -gōnon, which means angled. Web👉 Learn how to determine the sum of interior angles of a polygon. A polygon is a plane shape bounded by a finite chain of straight lines. A regular polygon ...

How many triangles make up a polygon? – Short-Fact

Weba triangle has 3 sides, therefore, n = 3 Substitute n = 3 into the formula of finding the angles of a polygon. Sum of interior angles = 180° * (n – 2) = 180° * (3 – 2) = 180° * 1 = … WebThree points (a triangle) ALWAYS define a flat plane. In other words, given any three points, you can always create a flat plane that can cut through all three points. However the same is not always true of four points. You can have four points all on a plane, but you can also have four points that aren't on a plane. Share Improve this answer flight sim steering wheel
