Question

Which undefined terms are needed to define parallel lines?

A. Point, line
B. Point, coplanar
C. Line, plane
D. Coplanar, line

Answer 1

Is it C??

Answer 2

Think about having those two things known, can you draw exactly one pair of parallel lines, or is it possible to draw multiple parallel lines that satisfy the given information?

Answer 3

So, first of all, can you draw a parallel line through that point? If not, then we have a problem. If so, then we need to figure out if it's the ONLY parallel line that we could draw through that point.

Answer 4

Or here's a line and a plane:

Can you draw a line in the plane that is parallel? If not, we have a problem. If so, is it the ONLY line we could draw in the plan that is parallel?

Answer 5

The answer is C

Answer 6

I humbly disagree.

Answer 7

Both with your answer itself and with your pointless statement of answers without explanation of any kind.
