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.
WebA square is a regular quadrilateral since all sides are the same length, and each angle is \ (90^\circ\). Its diagonals can be seen as perpendicular bisectors of each other. A square has four symmetry lines, each of which divides it into two identical halves.
WebMar 26, 2016 · You know what the formula for the number of diagonals in a polygon is, and you know that the polygon has 90 diagonals, so plug 90 in for the answer and solve for n: Thus, n equals 15 or –12.
