Introduction: Are you struggling to find the diagonal lengths of a trapezoid? Our trapezoid diagonal calculator can help you out! With just a few clicks, you can calculate the diagonal lengths of any trapezoid using the trapezoid diagonal formula. In this article, we will explain what a trapezoid is, how to calculate its diagonal lengths, and how to use our trapezoid diagonal calculator.

## Trapezoid Diagonal Formulas:

There are two common formulas to calculate the diagonal lengths of a trapezoid.

### Through sides

You can calculate the diagonal of the trapezoid across the sides. To do this, you need to know all four sides. The derivation of this formula is based on the parallelism of the bases of the trapezoid, and rectangular triangles, which form the height drawn from the vertices of the upper base.

d_1 = \sqrt{c^2 + db - \dfrac{d(c^2 - a^2)}{d-b}}

d_2 = \sqrt{a^2 + db - \dfrac{d(c^2 - a^2)}{d-b}}

where d_{1}, d_{2} are the diagonals lengths, and a, b, c, d are the lengths of the sides of the trapezoid.

### Through midline and height

In an isosceles trapezoid, the diagonal can be calculated by height and the middle line. Since the leg of the triangle lying on the larger base of the trapezoid consists of a smaller base and half the difference of the two bases in the properties of an isosceles trapezoid, it will be equal in value to the midline.

d = \sqrt{h^2 + m^2}

where d is the diagonal length, h is the height, and mis the midline.
