1. Explore Similar Solids
Lesson 12.7
Explore Similar Solids

2. Objective
Students will use properties of similar solids

3. Standard
11.0 – Students determine how changes in dimensions affect the perimeter, area, and volume of common geometric figures and solids.
8.0 – Students know, derive, and solve problems involving the perimeter, circumference, area, volume, lateral area, and surface area of common geometric figures.

4. Academic Language
Similar Solids

5. Explain Why

6. Similar Solids
Two solids of the same type with equal ratios of corresponding linear measures, such as heights or radii

9. Think/Pair/Share
Think back to similar polygons we studied earlier this year. What was true about the ratios of side lengths and perimeters? Side length ratios and Area ratios?
What do you predict with be the relationship between the ratio of the side lengths and volumes of similar polyhedra?

11. Things are just peachy!
