1 is a polygon. 2 and 3 are not.

Step-by-step explanation:

For the first shape:

This shape is a polygon because the sides of the shape are straight, have angles, and do not intersect.

For the second shape:

This is not a polygon because of the lines being bent and having curvature.

For the third shape:

This is not a polygon because the lines intersect at a point.

For a shape to be a polygon, it must have 3 or more straight sides, angles, and no intersections.
