Three are three angles in a triangle which all add up to exactly 180 degrees. A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices A, B, and C is denoted ABC. If all the three sides of a triangle are equal, than all 3 angles will be equal (each will be of 60 degrees).

- If you know 3 sides of a triangle (any triangle) you can apply the cosine formula:
- a^2 = b^2 + c^2 – 2 c b cosine A.
- If you have a right triangle the problem is easier. …
- tan ABC = AC / AB or if you want sine ABC = AC / BC or cosine ABC = AB / BC.
- Same thing for the other angle. …
- I hope this helps you with your homework.

The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.

There are several ways to find the angles in a triangle, depending on what is given: If the angle is between the given sides, you can directly use the law of cosines to find the unknown third side, and then use the formulas above to find the missing angles, e.g. given a,b,γ: If the angle isn't between the given sides, you can use the law of sines.
