Module 71 Interior and Exterior Angles Today you will need your Notes A blank piece of paper 2 3 1 180 Interior Angles of a Triangle Triangle Sum Theorem Proof 1 Take out your sheet of paper. Sections 3-1. What you’ll learn. How to identify the relationships between two lines or two planes. How to name angles formed by a pair of lines and a transversal. Vocabulary. . Parallel lines. Parallel planes. Objectives. State the triangle angle sum theorem and solve for an unknown angle in a triangle. Classify triangles based on measures of angles as well sides. State the triangle exterior angle theorem and solve for an unknown exterior angle of a triangle. Exterior Angles and Triangles. An . exterior angle. is formed by one side of a triangle and the extension of another side . (i.e. . . 1 ).. The interior angles of the triangle not adjacent to a given exterior angle are called the . Objectives. State the triangle angle sum theorem and solve for an unknown angle in a triangle. Classify triangles based on measures of angles as well sides. State the triangle exterior angle theorem and solve for an unknown exterior angle of a triangle. PART III. PARALLEL UNIVERSE.
