So this came up tonight with a friend while we were studying, he had an old SAT question that asked "How many sides does this shape have?". Below is a representation of the image provided.
After searching around and debating it, we came up with nothing. A polygon is defined as "consisting of a number of points and an equal number of line segments, with no three successive points collinear". But the question clearly stated "shape" and not polygon. Because of this, we're pretty stumped.
We then concluded on the proposition that this would have to depend on whether or not you were taught if lines have 1 or 2 sides.
