How many diagonals in a 8 sided polygon
WebAn octagon has 20 diagonals in all. This can be calculated using the formula, number of diagonals in a polygon = 1/2 × n × (n - 3), where n = number of sides of the polygon. Here, … WebDiagonals: A nonagon has 27 diagonals, which are lines that connect non-adjacent vertices of the polygon. The formula to calculate the number of diagonals in a nonagon is n (n-3)/2, where n is the number of sides. Symmetry: A nonagon has nine lines of symmetry, which divide the polygon into nine congruent parts.

WebThe formula for the number of diagonals in a polygon with n sides is: n(n-3)/2. where n is the number of sides of the polygon. In the case of a triangle, we have n = 3, so we can substitute this value into the formula and get: 3(3-3)/2 = 0. Explanation . A diagonal is a line segment that connects any two non-consecutive vertices of a polygon. WebFeb 1, 2024 · Hence the polygon is Nonagon. Question 5: How many diagonals does a polygon have if sides are 20? Solution: Put n = 20 in diagonals formula. Diagonals = (20 × (20 – 3))/2 = 170. Hence there will be 170 diagonals in a 20 sided polygon. Question 6: There are 405 diagonals in a polygon, find the number of sides it has? Solution:
WebThe number of diagonals in a regular polygon with 'n' sides is given by the formula: Number of diagonals = n(n-3)/2 Given that the regular polygon has 65 diagonals, we can set up the equation as follows: 65 = n(n-3)/2 Multiplying both sides by 2 to eliminate the fraction: 130 = n(n-3) Expanding the right-hand side: 130 = n 2 - 3n WebDec 22, 2024 · The standard definition of an octagon is something along the lines of, "An octagon is a polygon with 8 sides delimiting a closed area."
