In this activity, students will
1) set up a system for each problem.
2) solve for x and y.
3) use their x and y values to find additional information about each problem.
Students will need to have an understanding of properties of parallel lines, the base-angle theorem, supplementary angles, triangle sum theorem, Pythagorean theorem, and perimeter and area of triangles.
Two practice sets are given with answer keys.
