WebTo give one example, let's say that you proved the formula for the area of a trapezoid. Then you could easily find the area of a parallelogram IF you thought that it was a special kind of trapezoid where the two bases had the same length. There are a couple of other small sorts of things like that that could save you a little bit of thought. Suppose we have the following trapezoid: If we know the lengths of the sides and the angles of the bases, we can find the length of the diagonals of the trapezoid using the law of cosines: d1=a2+d2−2adcos(β)d_{1}=\sqrt{{{a}^2}+{{d}^2}-2ad~\cos(\beta)}d1=a2+d2−2adcos(β) … See more In the following examples, we apply the formulas detailed above to find the length of the diagonals of a trapezoid. Try to solve the examples yourself before looking at the solution. See more Put into practice what you have learned about the diagonals of a trapezoid and use the formulas to find the lengths of the diagonals. If you need help, you can look at the solved examples above. See more Interested in learning more about trapezoids? Take a look at these pages: 1. Area of a Trapezoid – Formulas and Examples 2.

WebTo find the measure of angle DAC, we must know that the interior angles of all triangles sum up to 180 degrees. Also, as this is an isosceles trapezoid, and are equal to each other. The two diagonals within the trapezoid bisect angles and at the same angle. Thus, must also be equal to 50 degrees. Thus, .
