Chapter 9 Student Learning Objectives SLO 9.1 I understand the angle relationships created by two parallel lines being cut by a transversal and can solve for missing angle measurements algebraically. SLO 9.2 I know the Triangle Sum Theorem and can apply its properties to find missing angle measurements. SLO 9.3 I can apply the Exterior Angle Theorem to find missing angle measurements. SLO 9.4 I can use the Pythagorean Theorem to solve real world problems, missing right triangle side lengths and the distance between two points.
