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. The side lenths have to be simlilar and two of the sides have to have the same angles.
2. One way you can find the missing side length is scale factor and another is ratios you divide top by bottom and then multiple and get the value of X
3.The other two side lengths are 10in because the scale factor is 2.5.
