Which statement is true?

f. perpendicular lines never intersect

g. parallel lines intersect at right angles.

h. intersecting lines have two points in common.

j. parallel lines never intersect.

Perpendicular lines intersect to form a right angle
So we can eliminate A

Parallel lines never intersect
So we can eliminate B

Intersecting lines CAN have 2 or more points but DO NOT always have 2 or more, meaning they can sometimes only intersect at one point.
So we can eliminate C

And as previously stated, parallel lines never intersect, which confirms what option J states.

So your answer is J
