How many possible non-congruent pentagram shapes (reflected and rotated are the same) can you make on a 5 x 5 grid?

A pentagram consists of 5 unit squares. Ex: 5 x 1 is a kind of pentagram (a rectangle), it could also be a stair pattern, or an L shaped pentagram.

I was playing blokus and came up with this question lol.
