Comparing Ratios of Measures of Similar Figures

How can you determine if two figures are similar? In this lesson, you will compare the ratios of measures of similar figures. To determine similarity, you will have to find the scale factor. If the ratio of the figures corresponding links are the same, the figures are similar. You will use your knowledge of similar triangles to help you in this lesson. Click the player button to begin.

Determining How Changes in One Dimension Affect Perimeter, Area, and Volume and Vice-Versa

When you change one dimension of a figure, the shape and volume of the figure are affected. In this lesson, you will determine how dimensional changes affect perimeter, area, and volume. You will also learn the reverse: if the perimeter, area, and volume are changed, the dimensions of the figure are affected. Your knowledge of solid figures will help you through this lesson.
