investigation 4 math reflections

1) For two parallelograms to be alike thier angles have to be the same and their ratios.

2)To find the missing side length you need to figure out the scale factor and then use it on the missing side length.

3)The other side lengths should be 10 beacause the scale factor is 2.5, so you you multiply 2.5 and 4 and you get 10.
