Question

Which basic geometric figure is labeled with either one capital letter or three capital letters?

A. Plane
B. Angle
C. Line
D. Point

Answer 1

An angle is labeled with either one capital letter or three capital letters

Solution-

Point-

As a point is 0 dimensional, so you just need 1 point to define a point.

Line-

As a line is 1 dimensional,so you need 2 points to define a line.

Plane-

A plane is 2 0r 3 dimensional, so you need 3 points to define a plane.

Angle-

An angle measures the amount of turn. An angles is labeled with a single letter at the vertex, as long as it is perfectly clear that there is only one angle at this vertex. Otherwise, it is named according to the intersecting lines with 3 letters.
