  1. 16 if you are only counting the match sticks, 17 if you count the square boarder around the match sticks, and 18 if your goofy like me and want to count the word. A square is a type of rectangle, but a "rectangle" is never a type of square; "rect"means right add the angle. Squares has four rect(right)angles and so are a typle of rectangle.
