Sure, let's break down the options to find the correct answer to this question.
- A. angle: An angle is formed by two rays (or lines) that share a common endpoint. Angles have two dimensions - their measure and often the rays forming the angle have lengths, which means they cannot have no width, length, or height.
- B. point: A point is a fundamental concept in geometry with no dimensions; it has no width, length, or height. It is merely a position or location in space. By definition, it fits the criteria stated in the question.
- C. line: A line extends infinitely in both directions and has one dimension - length. Even though it may be considered to have no width or height, it definitely has length, so it doesn't fit the criteria perfectly.
- D. ray: A ray starts at one point and extends infinitely in one direction. Like a line, it has length but no width or height. This means it also does not fit the criteria of having no width, length, or height.
Given the analysis above:
The only option that accurately describes an object in geometry with no width, length, or height is B. point.
So, the correct answer is:
○ B. point
