A diagonal bisecting a square creates two identical right triangles. The diagonal is the hypotenuse of a right triangles, so its length is the square root of the sums of the squares on the opposite...
The diagonal of a rectangle is the third and longest side of a triangle with sides the same as those of the rectangle, so its length is the square root of the sum of the squares of the lengths of the...
The formula for finding the diagonals of any polygon is: 0.5*(n2-3n) where n = the number of sides.A trapezoid has 4 sides so: 0.5*(16-12) = 2 diagonals
