Yes.
there is 15 perpendicular lines in a cube
I believe they do, and they have 2 perpendicular lines.

Spheres do not have any perpendicular lines.
Perpendicular lines are any two lines that intersect at a 90 degree angle.
Perpendicular lines are lines that cross at right angles. Intersecting lines can cross at any angle.
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.
Perpendicular lines are a subset of intersecting lines. The only difference is that perpendicular lines intersect at an angle of 90o, whereas intersecting lines can converge at any angle.
Any two intersecting lines (including perpendicular lines) will intersect at a single point.
