The axis of a right circular cone is perpendicular
to every radius or diameter of the base.
A cone has an infinite number of lines that can be drawn perpendicular to its surface. Specifically, any line drawn from the apex of the cone to a point on the circular base can be considered perpendicular to the radius at that point. Additionally, if you consider the vertical axis of the cone, any horizontal plane intersecting the cone's surface can also have multiple perpendicular lines.
No. A hyperbola is formed when a plane slices a cone perpendicular to the bases.
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.

= 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 that aren't perpendicular
PERPENDICULAR
Lines that intersect at 90 degrees are perpendicular lines
A rhombus has parallel lines but no perpendicular lines.
No. If the lines are parallel they will never meet or intersect at any point. If the lines are perpendicular they do intersect, but perpendicular lines are a special case of intersecting lines. Perpendicular lines are exactly 90 degrees from each other. Intersecting lines do not haveto be perpendicular... but perpendicular lines are always intersecting.
