About the Triangle Solver app
The Triangle Solver app allows you to determine the
length of a side of a triangle, or the measure of an angle
of a triangle, from information you supply about the other
lengths and/or angles.
You need to specify at least three of the six possible
values—the lengths of the three sides and the measures of
the three angles—before the solver 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 solver will calculate the remaining lengths
or angle measures.
The HP 39gII will alert you if no solution can be found, or
if you have provided insufficient data.
If you are determining the properties of a right-angled
triangle, a simpler input form is available by pressing the
menu key.
Getting started with the Triangle Solver app
The following example solves for the unknown length of
the side of a triangle whose two known sides—of lengths
4 and 6—meet at an angle of 30 degrees.
