a square or rhombus
Yes.
6 hex=6
There are more than two: A parallelogram has two sets of parallel line segments which may be of unequal length; A rectangle is a parallelogram that has line segments that meet at right angles; A rhombus has to sets of parallel line segments which are all of the same length; A square is a rhombus which has line segments meeting at right angles, or stated differently a square is a rectangle which has all line segments of the same length.
Opposite angles
Perpendicular line segments are line segments that intersect and make 90 degree angles.
Perpendicular line segments are line segments that cross with each other and form angles of 90 degrees.
You cannot have a shape without any line segments.
straight line,triangle,rays angles
a pentagon
Any closed shape with 6 line segments is a hexagon.
That seems to be true. Sides pretty much are line segments, and the angles are the end points.
