This study guide on lines and angles covers key terminology; line notation; parallel, perpendicular, and skew lines; and postulates and theorems about lines. It is available for download with free registration.

Students are challenged to identify and measure angles created by parallel lines and a transversal as well as complementary and supplementary pairs.

Students can review basic geometric terms using these self-check, multiple choice questions. Three levels of questions are provided.

Provides examples and a video lesson that introduce fundamental statements of geometry.
