How many diagonals in an isosceles triangle?
An isosceles triangle has three sides of equal length. To find the number of diagonals in an isosceles triangle, we can use the formula n(n-3)/2, where n is the number of sides of the polygon. In this case, an isosceles triangle has 3 sides, so plugging in n=3, we get 3(3-3)/2 = 0 diagonals. Therefore, an isosceles triangle has 0 diagonals.
