# Find the angles of the triangle

To find the angles of an irregular triangle, you will need to know the magnitude of all three of its sides. Knowing the sides of the triangle, using the formulas given below, you can calculate the angles in degrees. It is known that the angles of a triangle add up to 180°, so knowing two of them, you can calculate the third.
