This worksheet consists of ten geometry problems that require students to set up a correct quadratic equation and solve it. Topics include: betweenness, midpoint, supplementary angles, angle bisector, parallel lines cut by a transversal, triangle sum theorem, vertical angles, triangle exterior angle theorem, and base angles of an isosceles triangles are congruent. Students must check all possible solutions for x to ensure distances are positive and angle measures are appropriately between 0 and 180. Answer key is included.
