Similar Shapes

We have shifted our focus towards working with proportions, ratios, and rates. 

Proportional relationships are ones where numbers are related by multiplication and/or division.


To start we looked at 'similar shapes' or shapes that have the same angles, and the same proportions of sides. 

We explored similar shapes, created our own, and used a variety of strategies to identify whether shapes were similar to each other.

In your book you should have the following finished:

1) Using the similar triangle page draw a triangle that is similar to the 4 on the page.  How do you know its similar

2) On graph paper draw your own set of 4 shapes that are 'similar'.  In your book make sure you've proven their similar

- Do they have the same angles?

- Are the side lengths in proportion?

3) Solve the find the fakes sheet.  Record your thinking in your book.
