To find the average degree measure of the angles of a triangle, you need to know that the sum of the interior angles of any triangle is 180 degrees.
Step 1: Add up the degrees of all three angles in the triangle.
Let's assume the three angles are A, B, and C.
Step 2: Calculate the average.
To find the average, divide the sum of the angles by the number of angles, which is 3 in this case.
Average = (A + B + C) / 3
Step 3: Simplify the expression.
There is nothing else to simplify at this point.
Therefore, the average degree measure of the angles of a triangle can be calculated by using the formula (A + B + C) / 3, where A, B, and C represent the measures of the angles.
