It s a terrific tuesday for learning math

Family members:Glum & Tum

Imposters:Sum & Crum


It s a terrific tuesday for learning math

Angle measures are the same!


It s a terrific tuesday for learning math

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

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 …


It s a terrific tuesday for learning math

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

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

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

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

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?
