How many Diagonals does a trapezoid?

A trapezoid has two diagonals. These diagonals connect the non-parallel sides of the trapezoid, intersecting each other inside the shape. Since a trapezoid has four vertices, the number of diagonals can be calculated using the formula ( n(n-3)/2 ), where ( n ) is the number of sides; for a trapezoid, this results in two diagonals.
