Three undefined terms in mathematics: I. Point II. Line III. Plane The mathematical term parallel lines explicitly uses the undefined term(s) . The mathematical term perpendicular lines explicitly uses the undefined term(s) . The mathematical term line segment explicitly uses the undefined term(s) .

Explanation:

Here's the correctly written question:

Three undefined terms in mathematics:

I. Point

II. Line

III. Plane

1. The mathematical term parallel lines explicitly uses the undefined term(s) lines and plane.

2. The mathematical term perpendicular lines explicitly uses the undefined term(s) lines.

3. The mathematical term line segment explicitly uses the undefined term(s) points and plane.

So, in sumarry the answers are;

1. ll and lll

2. ll only

3. l and ll
