Question

Which statements are true regarding undefinable terms in geometry? Select two options.

A point in the form (x, y) has two dimensions.
A plane has a definite beginning and end.
A line has one dimension, length.
A point consists of an infinite set of lines.
A plane consists of an infinite set of lines.

Answer 1

Correct choices:
- "A line has one dimension, length." — True: a line is one-dimensional.
- "A plane consists of an infinite set of lines." — True: a plane contains infinitely many lines.

The others are false: a point is dimensionless (not two-dimensional), a plane has no beginning or end, and a point is not made up of lines.
