• It is made of straight line segments.
• Each segment touches exactly two other segments, one at each of its endpoints.

| concave polygon | A polygon that looks like it is “collapsed” or has a “dent” on one or more sides. Any polygon with an angle measuring more than 180°.
🗑

| sequence | An ordered list. For example: 2, 5, 8, 11,… is a sequence.
🗑
