[Free Registration/Login Required] This flipchart defines parallel lines and planes. It defines a transversal, the concept of alternate angles, and vertical angles.

[Free Registration/Login Required] This flipchart regards parallel lines and relationship of angles created by a transversal. Includes lesson on vocabulary, Jeopardy-style game, and quiz.

[Free Registration/Login Required] Explore the relationships between parallel lines and the rules of angle measurements.

Given information in a geometric context, students will be able to use informal arguments to establish facts about the angle sum and exterior angle of triangles, the angles created when parallel lines are cut by a transversal, and the...

Given the relationship(s) among a set of angles, the student investigates the patterns and makes conjectures about the geometric relationships, including angles formed by parallel lines cut by a transversal.

In this practice activity, students calculate angles created when two parallel lines are intersected by a transversal. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.

In this third unit of a course on Art Appreciation, students learn how to describe the technical aspects of an artist's work by discussing elements of art and principles of design. They also look at the stylistic qualities of an artist's...
