  1. Bellwork • Jerome and Jillian set up a lemonade stand. They sell lemonade and sweet tea. Each cup costs $0.50. Which equation shows how Jerome and Jillian can determine their total sales (S) based on the number of cups of lemonade sole (L) and the number of cups of sweet tea sold (T). • A. S=0.50(LxT) B. S=0.50(L+T) • C. S=0.50+(LxT) D. S=0.50+(L+T)

  6. Similarity in Things

  7. Similar Figures in Math Figures that have the same shape… but are NOT the same size. Do you see the similar figures in the photographs?

  8. Why Learn About Similar Figures? • Similar figures can be applied to solve real world problems. • For example, similar triangles can be used to find the height of a structure, the width of a river, the height of a tree etc. Great Pyramids of Egypt Olive Tree

  9. Similar Figures : Definition: Figures that have the same shape BUT are not the same size. Similar Use proportions to solve problems involving similar figures. Similar Figures The corresponding angles have equal measurements. The corresponding sides form a proportion.

  10. Similar • Same shape BUT NOT same size • Proportional in size

  11. Similar or not? 20in 32in 18in 24in

  12. Similar or not? 5 yd 2 yd 7 yd 2.8 yd

  13. Step 1 Write a proportion using corresponding sides. Step 2 Cross multiply. Step 3 Solve the one-step equation. Solving given similarity:
