WebApr 3, 2024 · The perimeter of the regular octagon is equal to the sum of all the sides, which is 8a. By joining the opposite vertices of the regular octagon, we will get the diagonals of the octagon. A regular octagon has 20 diagonals and their lengths are equal. The length of the diagonal of a regular octagon is a√(4 + 2√2). WebSolutions for Chapter 1 Problem 8T: Number of Diagonals A diagonal of a polygon is a line segment that connects nonadjacent vertices (corners) of the polygon. In the following polygons, the diagonals are shown by the blue line segments. Use a difference table to predict the number of diagonals in a. a heptagon (a 7-sided polygon) b. an octagon (an … WebWhile the octagon has five diagonals and the nonagon six diagonals, both the octagon and the nonagon have only three different types of diagonals as described in the earlier Instructables. Each diagonal can be regarded as forming the base of an isosceles triangle whose legs are radii of the polygon's circumscribed circle. some ways of maintaining a healthy body
