Question

All of the following are defined terms except _____.

ray
angle
plane
segment

Answer 1

Answer:- All of the given options are defined terms except plane.

Explanation :-

There are only three undefined terms in geometry :-

1) point 2) line 3) plane

The given options are ray, angle, plane and segment.

Thus the third option is the only undefined term i.e. plane .

Therefore, all of the given options are defined terms except plane.

Answer 2

Ray is a part of the line having one end point.

Angle is formed by the intersection of two lines .

A line segment is a part of the line having two end points.

But we cant define a plane .

So as we see that, ray, angle and line segment are defined but plane is not .

So the correct option is the third option .
