If the two lines are parallel, then you get 4 pairs of vertical angles. If the two lines are not parallel, then we get 6 pairs of vertical angles.

If there are only two parallel lines then 4 corresponding angles will be created
A triangular based pyramid has no parallel lines but it does have 4 faces, 6 edges and 4 vertices.

A rectangular prism has 3 sets of 4 parallel lines and 24 angles.

A right angle has no parallel lines, but it does have perpendicular lines that meet at right angles.
There are 56 pairs of congruent angles.
It has 1 set of 3 parallel lines and 3 sets of 2 parallel lines, and 18 angles (3 sides meet at each vertex)
When a transversal line cuts through parallel lines various angles are created such as equal corresponding angles and equal alternate angles as well as other types of angles.
Parallel lines do not meet and so cannot form an angle.
