The axis of a right circular cone is perpendicular
to every radius or diameter of the base.
No. A hyperbola is formed when a plane slices a cone perpendicular to the bases.
These lines are perpendicular: _|
Lines that aren't perpendicular
PERPENDICULAR

= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
Perpendicular lines intersect.

In a right circular cone a line from the vertex to the center of the circular base is perpendicular to the base. In an oblique circular cone that same line will not be perpendicular.
Lines that intersect at 90 degrees are perpendicular lines
A rhombus has parallel lines but no perpendicular lines.
Octagons have no perpendicular lines.
I believe they do, and they have 2 perpendicular lines.
