A plane and a line sometimes never or always intersect in a single point?

A given plane and a given line don't necessarily have to intersect at all.
If the line is parallel to the plane, then they never do.
The line can also be in the plane, and then every point on the line is also
a point in the plane.
The most likely case, though, is that the line is not parallel to the plane and
not in it. In that case, their intersection is a single point.
So I guess the best answer from the allowed choices is 'sometimes'.

Does three altitudes of a triangle intersect at a vertex always never or sometimes?
Always for it to be a complete triangle with three altitudes it would have to intersect at a vertex.
When chords intersect in a circle the vertical angles formed intercept conruent arcs always sometimes never?
Sometimes
Is the angle bisector of a scalene triangle ever intersect at a single point?
never
Lines never intersect?
Parallel lines never intersect
How many ways can two different lines intersect?
It depends on how you define "ways" and how you define "lines" and how you define "intersect" and what kind of geometry you're talking about, but in Euclidean geometry, lines either never intersect, or they intersect at a single point, or they can intersect at all points within the lines.
Do perpendicular lines always sometimes or never intersect?
Perpendicular lines always intersect and make 90 degree angles. Parallel lines never intersect with each other.
Are a line and a plane that do not intersect always sometimes or never skew?
A line and a plane that do not intersect are always skew. Skew refers to two or more lines or planes that are not parallel and do not intersect. Since a line and a plane are different-dimensional objects, they will never intersect and will always be skew.
Does three altitudes of a triangle intersect at a vertex always never or sometimes?
Always for it to be a complete triangle with three altitudes it would have to intersect at a vertex.
Does the three medians of a triangle intersect at a point in the interior of the triangle always sometimes or never?
sometimes
Does two intersecting planes always sometimes never intersect in exactly one point?
Never.
When chords intersect in a circle the vertical angles formed intercept conruent arcs always sometimes never?
Sometimes
If two lines intersect then they lie in one plane. Is this true always sometimes or never?
always. if two lines intersect, then exactly one plane contains the lines.
Do the perpendicular bisectors of a triangle always sometimes or never intersect on the triangle?
The perpendicular bisectors only intersect on the triangle when it is an isosceles right triangle.
Do the angle bisectors of a triangle always sometimes or never intersect on the triangle?

Two lines which are always the same distance from each other and never intersect?
Parallel lines are always the same distance from each other and never intersect.
Do skew lines always intersect?
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
Is the angle bisector of a scalene triangle ever intersect at a single point?
never
