Question

complete the sentence.
two line segments can intersect in ______.
a line \t three points
two points \t one point

Explanation:

A line segment is a part of a line with two endpoints. When two line segments intersect, they can share at most one common point (unless they are coincident over a segment, but the options don't suggest that). A line is infinite, segments can't intersect in a line. Three or two points would require more than the maximum intersection of two segments (which is one point or none, but among options, one point is correct as two segments can meet at a single point).

Answer:

one point
