Given a pair of similar figures, including dilations, students will be able to generalize that the lengths of corresponding sides are proportional.

Given two polygons, try to map one onto the other using angle-preserving transformations, and determine whether they are similar. Transformations are done in "intuitive mode." Students receive immediate feedback and have the opportunity...

[Free Registration/Login may be required to access all resource tools.] This study guide looks at similar polygons, scale factor (ratio), and triangle similarity.

[Free Registration/Login may be required to access all resource tools.] An overview of altitudes and geometric mean is provided in this study guide.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students learn to dilate a figure. Students examine guided notes, review guided practice, watch instructional videos and attempt practice problems.

[Free Registration/Login may be required to access all resource tools.] This study guide reviews ratios, proportions, and cross-multiplication.

The purpose of this lesson is to help students apply math concepts concerning similar triangles and trigonometric functions to real life situations. The students learn how to take these concepts and use them to find measurements of...

[Free Registration/Login may be required to access all resource tools.] This study guide looks at the definitions and units for perimeter, area, and circumference, and at the perimeter and area of different shapes, including regular...

Use this interactive tool to find the volume of a pyramid. Try different figures for the height and the base to see how these affect the volume. Properties of pyramids are explained, how to calculate the volume using a formula, what an...

This interactive exercise focuses on volume equations, measurement, and problem solving skills to compare the volume of 3D figures constructed from similar amounts of construction materials.

This is a glossary entry for the term "Puns" including a definition and an extensive list of examples.
