An interactive applet and associated web page that show the concept of adjacent angles (two angles that share a common leg). The applet shows three line segments with a common endpoint. The user can move the center one and see that the angles on both sides (the adjacent angles) of it are affected. Applet can be enlarged to full screen size for use with a classroom projector. After use in the classroom, students can access it again from any web browser at home or in the library with no login required. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
This video from WOUB Athens, presented as a parody of a popular TV network reality show, will help high school students review and prepare for the Ohio Graduation Test in Mathematics.
This activity allows the user to practice important angle vocabulary. This activity would work well in mixed ability groups of two or three for about twenty to twenty-five minutes if you use the exploration questions and ten to fifteen minutes otherwise
Student groups are provided with a generic car base. The groups then design a device/enclosure that will protect an egg on or in the car as it is rolled down a ramp at increasing slopes. Students will be expected to perform basic mathematical calculations using their data.

This lesson plan will help the students visualize the different angles (corresponding, alternate interior, and same-side interior) when coplanar lines are cut by a transversal.
Geometry is concerned with the various aspects of size, shape and space. In this unit, you will explore the concepts of angles, shapes, symmetry, area and volume through interactive activities.
CK-12's Geometry - Second Edition is a clear presentation of the essentials of geometry for the high school student. Topics include: Proofs, Triangles, Quadrilaterals, Similarity, Perimeter & Area, Volume, and Transformations.
This geometry lesson discusses parallel lines and the relationship of angles that form when other lines, called transversals, cross them. [Geometry playlist: Lesson 4 of 31]
This geometry lesson continues the discussion of parallel lines and the relationship of corresponding angles that form when other lines, called transversals, cross them. [Geometry playlist: Lesson 5 of 31]
This book is a "flexed" version of CK-12's Basic Geometry that aligns with College Access Geometry and contains embedded literacy supports. It covers the essentials of geometry for the high school student.
A structured geometry program teacher edition of daily lesson plans and teacher supports to accompany the College Access Reader: Geometry student edition.
