        Lines, Angles, and Triangles: Lesson 1 - Introducing Lines and Angles

        Introducing Lines and Angles is the first of eight self-paced lessons in the “Lines, Angles, and Triangles” section of KET’s GED® Geometry Professional Development Online Course. This lesson introduces lines and angles, including how to name angles and recognize degrees. It also extends the discussion of lines to two important pairs of lines that are featured in later lessons⎯parallel lines and perpendicular lines.

        NOTE: This course was created based on the 2002 GED® math test. The geometry instruction in this course is still valid, however, for up-to-date information about the 2014 GED® math test, please visit KET’s GED® Test Info: Mathematics online course.
