Triangles Calculator for Android

11 things about Triangles Calculator

1. For both right angled triangles or non-right angled triangles once you have specified enough information for the calculations to be done then the answers appear on the diagram and a full explanation is given below to explain how the answers were arrived at.

2. 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.

3. 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.

4. 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.

5. If you have specified invalid information then the diagram will update to show this information but none of the unknown sides or angles will be calculated.

6. 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.

7. To specify known parts of the triangle click on the side or angle on the diagram that you know.

8. Press enter and the value will be used to update the diagram.

9. You now click on the diagram to select the next value.

10. The label to the left changes to show that it is this value to be specified, and so on.

11. The label at the top left will change to specify that side or angle.
