Including its diagonals there are 6 perpendicular lines
There are no perpendicular lines in a regular 6 sided hexagon.
Six parallel sides in pairs? Sounds like a cube.
When two lines are parallel, they have the same slope. For example:y=5x-3 andy=5x+9These lines are parallel, because they have the same slope.When two lines are perpendicular they have negative reciprocal slopes. For example:y=2x-6 andy=-1/2x+2These lines are parallel, because they have negative or opposite reciprocal slopes.
One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.
