Parallel Lines Teacher Resources

Students investigate the effects of industry on natural features. They discuss the industrial revolution, and create a drawing of a river with one half illustrating pre-industrial revolution time, and the other half representing the...

Students investigate the symmetry that is found in nature. They view shapes and patterns in nature while looking at images. Students look for tessellations while obtaining photographs with a digital camera. The information is used for...

Material to supplement classroom instruction on parallel lines: a lesson on angles with parallel lines, a practice quiz, and a link to an investigation on angles with parallel and non-parallel lines.

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...

Lines that are parallel have a very special quality. This tutorial takes a look at parallel lines and how they are different from other types of lines. [4:06]

Students learn how to write a linear equation from a parallel line and a point. The tutorial consists of a detailed example that explores the mathematics concept. [3:56]

Explains the basic concept of parallel lines in Geometry with step-by-step instructions and methods for solving specific problems on your own relating to this topic.

Alex and his friends are studying for a geometry test and one of the main topics covered is parallel lines. They each write down what they think it means for two distinct lines in a plane to be parallel. Students are asked to analyze...

Students can use Cabri Jr. to construct parallel lines and transversals. They will make conjectures about the angles that are formed.

Students explore relationships in various angles formed by 2 parallel lines and a transversal.

The goal of this task is to prove the slope criterion for parallel lines. Aligns with HSG-GPE.B.5.

Sal draws parallel line segments with given points.

Cabri Jr. activity to study the properties of parallel lines.

In this activity, students will explore the proportional relationships involved in multiple parallel lines being cut by transversals. These relationships are approached through exploration of a sail design problem, where students are to...

Explains how to determine the measures of all the angles formed when parallel lines are cut by a transversal based on the measure of one angle. Explains how to use corresponding congruent angles to determine if lines cut by a transversal...
