• Name Angles (IXL)

• Identify Complementary, Supplementary, Vertical, and Adjacent Angles (IXL)

• Find the Measures of Complementary, Supplementary, Vertical, and Adjacent Angles (IXL)

• Write & Solve Equations Using Angle Relationships (IXL)

In this video, Mr. J goes through 3 examples on what vertical angles are, how to identify vertical angles, and how to find the missing measure of vertical angle pairs.

In this video, Mr. J goes through 4 examples on what adjacent angles are and how to identify adjacent angles.

• Scale Drawings of Polygons (IXL)

• Scale Drawings: Word Problems (IXL)

• Scale Drawings: Scale Factor Word Problems (IXL)

In this Khan Academy video, Sal finds a missing side length in a scale drawing when given either a set of corresponding side lengths or one side length and the scale factor. 

This video explains how scale drawings work. Discusses the two types of scale drawings (enlargements and reductions) and goes through several examples.

In this Khan Academy video, Sal explains how to identify the scale factor used to create a scale copy.
