Discover The Number Of Diagonals In A Regular Pentagon For Enhanced Math Solutions
How Many Diagonals Does a Regular Pentagon Have?
A regular pentagon is a polygon with five equal sides and five equal interior angles. A diagonal is a line that connects two non-adjacent vertices of a polygon. To calculate the number of diagonals in a convex polygon, use the formula n(n-3)/2, where n is the number of sides. Substituting n = 5 into this formula, we get 5(5-3)/2 = 5(2)/2 = 5 diagonals. Therefore, a regular pentagon has 5 diagonals.
