To find the angle measures in a triangle, remember that the sum of the angles in any triangle is 180 degrees. If you know two angles, subtract their sum from 180 to find the third angle. For right triangles, one angle is always 90 degrees. Use trigonometric ratios (sine, cosine, tangent) if you know sides but need angles.
