About the Triangle Angle Calculator
The interior angles of any triangle always add up to exactly 180 degrees, so knowing two of them is enough to find the third by subtraction.
Formula: Angle 3 = 180° − Angle 1 − Angle 2
If the result is zero or negative, the two given angles are not valid for a real triangle.
