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?

1) in order for 2 parallelograms similar they both must have a similar scale factor for the side lenghts. Another way you will know two parallelograms are similar by looking at the angles. If both parallelograms have the same angles and the SF inorder to be the same

2) One way you can find a missing side length from a pair of similar figures is by deviding two similar side lengths that both figure have in common. So if the figures have atleast one ajescent devide both of those numbers do get a number then multiply the other side by the number that you got from deviding the last 2 numbers and you will get the other missing side length on the figure

1) the missing side lengths would be both 10 because
