Presentation transcript:

To identify and apply similar polygons Using a knowledge of extended proportions, students will define and make explicit use of the term “scale factor” between similar polygons. They will also solve equations involving scale factor.

7-2 Quiz The following questions are to help you decide if you understood today’s lesson. Please make sure you ask questions when you miss one so you won’t make the same mistakes in your homework. Be sure to record the number you got right on your portfolio sheet!

1. ABCD ~ WXYZ. AD = 6, DC = 3, and WZ = 59. Find YZ 1. ABCD ~ WXYZ. AD = 6, DC = 3, and WZ = 59. Find YZ. The figures are not drawn to scale. 118 29.5 21.7 177 Y Non-Response Grid

2. You are reducing a map of dimensions 2 ft. by 3 ft 2. You are reducing a map of dimensions 2 ft. by 3 ft. to fit to a piece of paper 8 in. by 10 in. What are the dimensions of the largest possible map that can fit on the page? Non-Response Grid
