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) For two parallelograms to be similar the angle measures need to be in the same order
2) To find a missing side lenghth in a pair if two similar figures you can multiply or divide a corosponding side by the scale factor and you will have the answer
3) The other sides should be 10 inches because if you divide 3 by 7.5 you get the scale factor of .4

7.5/3 = 2.5. That is the scale factor to use then to multiply by 4. Also, what else needs to be the same for shapes to be similar? 6/9.
