Question

Peter draws lines r and s as two distinct parallel lines. Select each statement that is true about lines r and s. Lines r and s have exactly one point in common. Lines r and s form at least one right angle. Lines r and s will never intersect. Lines r and s have no point in common.

Answer 1

2 Answers: Choice C, Choice D

=========================================================

Let's go through the answer choices one by one

• A) This is false because parallel lines do not cross or intersect. They cannot have a point in common.
• B) This is false because lines need to cross in order to form a right angle.
• C) This is true. Parallel lines never intersect. They are the same distance away from one another at any point along either line. One example of parallel lines are the metal tracks in a railroad.
• D) This is true. Having a point in common means a point is on both lines at the same time, but parallel likes never cross. So they have no points in common.
