Final answer:
The sum of the measures of the angles in a triangle is always 180 degrees.
Step-by-step explanation:
In a triangle, the sum of the measures of the angles is always 180 degrees. This is known as the Angle Sum Theorem. To write an equation, let's assume the three angles are a, b, and c. The equation would be a + b + c = 180. By solving this equation, you can find the measures of the angles in the triangle.
