Students define and identify shapes by name. In this geometry lesson, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.

Students create a bridge using engineering and geometric concepts. In this geometry instructional activity, students identify the missing measures of polygons sides and angles. They work together to solve real life situation using...

Learners demonstrate the motion of waves. In this wave lesson, students demonstrate the various attributes to waves and the properties through a variety of hands-on activities.

High schoolers explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. High schoolers identify different geometric...

Students investigate the concept of a Limit and how it is used in a variety of problematic situations. They fold paper to help illustrate how to form equilateral triangles and explain how all the angles are the same. The lesson includes...

Students measure and label specified angles. In this angles lesson, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct definition. This lesson...

Explore the world of transversals in this mini-lesson. Learn about transversals, transversal lines, and angles. There are transversal examples and a few interesting practice questions at the end of the page to strengthen your concepts of...

MathWorld offers a brief definition of a transversal line provided by MathWorld.

In this lesson on parallel lines and transversals, 8th graders explore the characteristics and how to draw parallel and transversal lines and explore the relationship between them.

The student will verify theorems about angles formed by parallel lines cut by a transversal and apply these relationships to solve problems.

Investigate vertically opposite, corresponding, and alternate angles formed by parallel lines and a transversal using this highly interactive Learn Alberta math. Be sure to follow the link to the printable activities, solutions, learning...

Get the definition for parallel lines and explore angles associated with parallel lines.

This study guide on angles and transversals covers key terms, angle types formed by transversals, postulates and theorems about transversals, and how to prove if lines are parallel or perpendicular. It is available for download with free...
