Triangle Calculator

The triangle calculator can be used to solve unknown sides or angle of a triangle given three know components.

You first need to select a Method for the triangle calculation. There are 5 methods available to choose from and you can decide what method to use based on your known triangle components.

Side-Side-Side: Use this when you know the length of the three sides of a triangle.
Angle-Side-Angle: Use this when you know two angles and the distance between them.
Side-Angle-Angle: Use this when you know two angles and one side. The know side must not lie in between the two known angles.
Side-Angle-Side: Use this when two sides and the angle between them are known.
Side-Side-Angle: Use this when two sides and one angle that is not between the known sides are known. This method will produce two solutions.

After you choose the solution method and enter the known components of the triangle, press the View Results button to complete the calculation.
