Parallel Lines Teacher Resources

This is a terrific set of activities related to art instruction. Includes matching, concentration, flashcards, and a word search. Great for art students looking for a fun way to review vocabulary terms.

The lesson investigates special pairs of angles. Topics explored include complementary, supplementary, and vertical angles. Students learn about the concept and view diagrams and exercises with solutions.

This tutorial shows you how to find x so two lines are parallel. [2:47]

Take a look at this tutorial to see how to find the slope of your line and use that slope, along with the given point, to write an equation for the line in slope-intercept form. [4:53]

Take a look at this tutorial to see how to find all the missing angle measurements by identifying vertical, corresponding, adjacent, and alternate exterior angles. [4:43]

Vertical angles are always congruent to one another. Take a look at this tutorial to learn about and see how to identify vertical angles. [4:07]

View this tutorial to see how to use what you know about complementary angles to find a missing angle measurement. [3:20]

Complementary angles always add up to 90 degrees. Watch this tutorial to learn about complementary angles and see how to use this knowledge to solve a problem involving these special types of angles. [3:20]

Take a look at this tutorial as it introduces you to supplementary angles and shows you how to use them to solve for a missing angle measurement. [3:20]

Study inscribed angles in semicircles and quarter-circles. What conjectures can you make about the measure of an inscribed angle in semi- or quarter-circles?

In this tutorial, students will learn how to find missing angle measurements by first creating an equation. [4:20]

In this tutorial, you'll see how to use your knowledge of supplementary angles to set up an equation and solve for a missing angle measurement. [3:41]
