Trapezoid

The height of a trapezoid is given by:Example of a trapezoid with diagonals, angles and side lengths


h=b*sin(C)=d*sin(D)

or you can use this more complicated formula, if the side lengths are the only given data:

h=frac{2}{a-c}*sqrt{s*(s-a+c)*(s-b)*(s-d)}

where a,b,c and d are the side lengths, a > c and s=frac{a+b-c+d}{2} .

Calculate the height of a trapezoid with the side lengths given

Please enter the side lengths.
a must be greater than c.
