Triangle Solver app

The Triangle Solver app enables you to calculate the length of a side of a triangle, or the size of an angle in a triangle, from information you supply about the other lengths, angles, or both.

You need to specify at least three of the six possible values—the lengths of the three sides and the size of the three angles—before the app can calculate the other values. Moreover, at least one value you specify must be a length. For example, you could specify the lengths of two sides and one of the angles; or you could specify two angles and one length; or all three lengths. In each case, the app will calculate the remaining values.

The HP Prime will alert you if no solution can be found, or if you have provided insufficient data.

If you are determining the lengths and angles of a right- angled triangle, a simpler input form is available by

tapping .
