Polygons - Math is Fun

WebPolygons. A polygon is closed plane figure formed by the joining of three or more straight lines. A regular polygon is one that has equal sides and equal interior angles. n-gons, so a 23 sided polygon would be called a 23-gon. The sum of the measures of the angles of a convex polygon with n sides is (n - 2)180. WebOctagons have 8 sides so again, we need to adjust the formula accordingly: sum of internal angles = (8 - 2) x 180°. 1080° = 6 x 180°. In a regular octagon, one angle would be worth: 1080° ÷ 8 ... WebWe can learn a lot about regular polygons by breaking them into triangles like this: Notice that: the "base" of the triangle is one side of the polygon. the "height" of the triangle is the "Apothem" of the polygon. Now, the area of a triangle is half of the base times height, so: Area of one triangle = base × height / 2 = side × apothem / 2. 7 gold streaming the coach
