Similar vs Congruent

Similar vs Congruent-- Had a great question from one of my kiddos on Friday.  Are all congruent shapes similar?  The class was pretty split on this one.  I told him I thought yes, but we are still debating.  Does a shape have to be a different size to be similar?  Or can shapes that are the same size be similar?  We would love any input on this :)
Thanks

  1. The question seems a little too open ended to give definite answer to. Perception comes into play here. At first glance, I would look at a star as a very different shape next to a triangle. A deeper look would would show us that there are actually several triangles making up the star shape. Does this make them similar, congruent or both?
