Lesson 12.7
Explore Similar Solids
Objective
• Students will use properties of similar solids
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.
Academic Language
• Similar Solids
Explain Why
Similar Solids
• Two solids of the same type with equal ratios of corresponding linear measures, such as heights or radii
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?
Things are just peachy!
