How do you determine if a triangle can be formed when you are given three side dimensions?
You are then going to be working with a partner looking at a variety of side lengths. You will need to determine how many different triangles you can create depending on the side lengths that you have to work with. This is Investigation 3.4 in your packet.
Then we are going to look at the concept of dilation.
Dilations
A dilation is a non-rigid transformation, which means that the original and the image are not congruent. They are, however, similar figures. To perform dilations, a scale factor and a center of dilation are needed. If the scale factor is larger than 1, the image is larger than the original; if the scale factor is less than 1, the image is smaller than the original.

Then we are going to practice a dilation of your own using graph paper.
