This app shows all of the details of using algebra and trigonometry to solve for the measures of the three sides, three angles, and area of a right triangle given the length of one side or the area and one other measurement. All cases are shown, including those where it is the area that is given. A scale construction of the triangle is also given. The triangle may be rotated by moving point A, and it can also be reflected via a check box, so that any desired orientation of the triangle can be illustrated, e.g. for any of many practical applications of this process.
