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 …

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)
