Mathematical Similarity Summary

True Or False?

Q1: Any two rectangles are similar…
That is not always true, some rectangles could be 3 by 5 and the other is 6 by 7. The second one would have to be 6 by 10, then they have a scale factor.
Q2: Any two equilaterals are similar…
This is true because they will always have a scale factor from one to another. This is because all sides are the same length.
