1. Can you find the scale factor given to similar shapes?
2. Can you find an unknown side length when given similar shapes?
3. Can you provide the relationship of scale factor to perimeter between two similar shapes?
4. Can you provide the relationship of scale factor to area between two similar shapes?

Investiagtion 2.1 Mug Wump!

Students are currently graphing Mug Wump and his impostors on coordinate graphs.  They are investigating how a "rule" will change the dimensions of an original shape.  Some rules will allow the shapes to be similar and some will not.  

Do you have any ideas which rules will change an image to be similar?

Use the following link to help you in plotting points on a coordinate graph.
