Answer the following questions on YOUR blog as a post. Use the same title as mine for your post. Write your answers in complete sentences! An easy way to do this is to copy and paste the questions below onto your post and then put your answers in a different color!
1) What has to be the same in order for two parallelograms to be similar?

2) Describe a way to find a missing side length in a pair of similar figures.

3) I have a small isosceles triangle with a base of 3 inches and other sides are 4 inches.I want to create a similar isosceles triangle with a base of 7.5 inches.What should the other side lengths be and why?

Something has to be the same in order for a parallelograms to be similiar are its angles.

A way you can find a missing side length is by finding the ratio. If the ratio is the same then that means that the shape is the same.

The side lenghts for the other sides are that are missing are 10 inches. I know this because the scale factor is 2.5 and when you do 2.5x4 the answer is 10.
