Question

geometry 1 - 1: measuring segments and angles
a line is an infinite number of points on a straight path that extends in two opposite directions with no end and has no thickness.
a plane is an infinite number of points and lines on a flat surface that extends without end and has no thickness.
noncollinear → not on the same line
collinear → on the same line

1. what are the 3 undefined terms

non - collinear
point
line
plane

Explanation:

In geometry, the three undefined terms are point, line, and plane. A point has no size, a line extends infinitely in two opposite directions with no end and no thickness, and a plane extends without end and has no thickness. Non - collinear is a property related to points and lines, not an undefined term.

Answer:

B. Point, C. Line, D. Plane
