Monday, November 22 Make sure your name is on Practice 6-2 and it is completed. (If it’s not finished, let me know!) Fill in planner. Today’s homework is Practice 6-3 Bell Work (solve each proportion)

Today’s Objective SWBAT Why? Solve problems that involve similar figures Solve problems that involve scale drawings Why? To solve real world problems involving maps

Key Concept equal proportion

Vocabulary The same shape, but are not necessarily the same size. Using similar figures to compute distances that are difficult to measure directly An enlarged or reduced drawing that is similar to an actual object or place. The ratio of a distance in the drawing to the corresponding actual distance is the scale. Is similar to

Is this bigger or smaller in real life?

Is this bigger or smaller in real life?
