Which of the following is not an undefined term?
Which of the following is not an undefined term?
The correct option is B angle
Explanation for Correct answer:
Option (B):
Undefined terms are the terms that are not formally defined in geometry.
An angle has been defined in geometry as the figure formed by two rays meeting at a common endpoint.
So, the angle is not an undefined term.
Explanation for incorrect answers:
Option (A):
A line really does have dimension. That really is, its length is only one dimension long. However, neither the thickness nor the length of the line can be determined.
Thus, the Line is an undefined term.
Option (C):
A plane, like a line, has no thickness, which means that the thickness of its edges cannot be determined. It could also be extended in any direction indefinitely.
As a result, the plane is undefined.
Option (D):
A point seems to have no length, width, or thickness. Despite the fact that it is represented as a dot, there is no specific way to represent the dot.
As a result, the point is an undefined term.
