Math Reflections Investigation #4

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?
For a parallelogram to be the same you have to have the same angles and ratio.

2) Describe a way to find a missing side length in a pair of similar figures.
Find the scale factor from one figure to another.

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?
the other sides should be 10 because to get from a to be you have to do 3 times 2.50 and you get 7.5 so 4 time 2.50 is 10
