Do you need to learn how to determine the angles and lengths of a Right Angle Triangle? Need to clearly understand which of the sine, cosine and tangent ratios to use? Need to know how to determine the angle when you know two of the sides. If the answer is Yes to any of these questions then this App is for you. The Angles Calculator not only calculates the answers for you but it also tells you how it did it so you can understand how and when to apply the rules for right angle triangles.
Now that you know right angled triangles what about non-right-angled triangles? It all the same problems but with different formula to apply to calculate the unknown sides and angles.
The App is made up of two parts each with a diagram - one part for right angled triangles and one for non-right angled triangles. The Tab at the top allows you to select which one you want to do.
To specify known parts of the triangle click on the side or angle on the diagram that you know.
