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 .
Getting started with the Triangle Solver app
The following example calculates 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.
