WebA polygon is a plane (2D) shape with straight sides. To be a regular polygon all the sides and angles must be the same: Other Common Polygons These are 2D shapes, and they are polygons, but not regular polygons: Curved Shapes These are also 2D shapes, but are not polygons because they have curves:
Web15 jun. 2024 · The polygon has 13 sides. Example 5.27.4 How many degrees does each angle in an equiangular nonagon have? Solution First we need to find the sum of the interior angles; set n = 9. (9 − 2) × 180 ∘ = 7 × 180 ∘ = 1260 ∘ “Equiangular” tells us every angle is equal. So, each angle is 1260 ∘ 9 = 140 ∘. Example 5.27.5
WebThey have four sides. The sum of all interior angles is 360°. They have two diagonals. A quadrilateral can be regular or irregular. A regular quadrilateral must have 4 equal sides, and 4 equal angles, and its diagonals must bisect each other. Square is the only quadrilateral that satisfies all these conditions.
