Solution to the Problem:
Use the following geometric theorems moving from one vertex to another:The sum of the measures of the angles of a triangle equals 180 degrees.
If two angles form a line (or a linear pair), then they are supplementary, so they add up to 180 degrees.
Vertical angles are congruent.
If two lines are parallel, the alternate interior angles are congruent.
The answers to the twenty-six angles are as follows:
