Family members: Glum & Tum Imposters: Sum & Crum
Yes, the findings support the prediction that the impostors will be Sum and Crum! Impostors are those who have different scale factors applied to the x and y coordinates. In other words…rules that the x & y are multiplied by the same number make family members!
2 questions before we move on… • Can you describe to your neighbor what scale factor means? • the # you multiply the lengths of an original figure by to stretch or shrink it • What might be some examples in the real world where scale factors might be used? • Movie screens, logos, billboards, blue prints, photographs, copied images, clip art …
You Need: Calculator 2.1 Lab sheet from 2.1 Grid Sheet yesterday BIG IDEA: Drawing and Identifying Similar Figures Make sure your notebook cover sheet looks like this: #. Date Brief Description 1. 10-3 S&S Problem 2.1 day 1/ ACE (1 a-e) 2. 10-4 S&S Problem 2.1 day 2/ ACE (14-15)
Let’s look back at yesterday’s lab sheet on the back of your homework… • How would you describe to a friend the growth of the figures that you drew? • They all increased in size…taller…or wider…or both! • Which members seem to belong to the Wump family? And which do NOT? • Mug, Zug and Bug have the same shape but Lug and Glug are distorted.
Are Lug and Glug related? • NO! • Lug is WIDE and SHORT • Glug is NARROW and TALL
How do the corresponding angles of the 5 characters compare? • Family members (Mug, Zug, and Bug) have the SAME angle measures! • The others (Lug and Glug) do NOT have the same angle measures…EXCEPT for the right angles, of course!!
Now, let’s look at the corresponding lengths of the characters… ► leg heights 1, 2, 3 ► nose widths 2, 4, 6 ► mouth widths 4, 8, 12 Did you notice any patterns?
Make sure your notebook cover sheet looks like this: • #. Date Brief Description • 1. 10-3 S&S Problem 2.1 day 1/ ACE (1 a-e) • 2. 10-4 S&S Problem 2.1 day 2/ ACE (14-15) Homework is on page 33 in Stretching and Shrinking
