Practice with corresponding sides and points in scale drawings.

[Free Registration/Login may be required to access all resource tools.] Recognize the ratio of corresponding side lengths of similar figures as scale factor.

Students can use Cabri Jr. to discover two properties of similar triangles: corresponding angles are congruent and corresponding sides are proportional.

Using the USA TODAY Infograph, 'Wing tabs save fuel', ratios and proportions will be used to explore the concept of similarity between a drawing/model and the actual dimensions. The effects of dilation (size change) on an image and...

This lesson will define the phrase corresponding parts (e.g. angles, sides, etc.). It is 5 of 5 in the series titled "Corresponding Parts."

Students explore the relationships of angles formed when two parallel or non-parallel lines are cut by a transversal. This activity investigates the terms: Transversal, corresponding angles, alternate interior angles, alternate exterior...

Students can use a map of Washington, DC, to travel to/from different tourist locations using vertical angles, corresponding angles, alternate interior angles, alternate exterior angles, same-side interior angles, and linear pairs.

This learning tutorial describes the characteristics of similar figures and how to use scale factor and proportions to determine missing side lengths. The lesson includes PowerPoint presentations and videos demonstrating how to solve...

In this activity Using the USATODAY infograph, "Ballooning inside the box", students will explore geometric relationships using similar triangles. Identifying triangles with two pairs of congruent angles to explore similarity properties...

In this lesson on similar figures and proportionality, students explore how to identify if figures are similar by applying their knowledge of corresponding angles and sides.

In this activity, students learn and increase their knowledge about the angles formed when parallel lines are cut by a transversal.

Students will investigate patterns to make conjectures about geometric relationships and apply the definition of similarity, in terms of a dilation, to identify similar figures and their proportional sides and congruent corresponding...

Full text of the Federalist Papers which express the general views of the individuals who formed the Federalist Party. Each paper is identified by date, subject, author and place of publication and is available for reading by clicking on...
