WebOct 8, 2024 · A heptagon has 7 sides and 7 internal angles. It also has 7 external angles. A regular heptagon has 7 equal sides How many sides and vertices does a heptagon have? A... WebThe formula that is used to find the number of diagonals in any polygon is, Number of diagonals = n (n-3)/2; where 'n' represents the number of sides of the polygon. In this case, there are 8 sides in an octagon. After substituting the value of 'n' = 8 in the formula, we get, Number of diagonals = n (n-3)/2 = 8 (8 - 3)/2 = (8 × 5)/2 = 20.
