Question

Which of these cannot be represented by a point?

a) Tip of the needle b) A vertex of a triangle

c) tip of pen d) length of a pencil box​

Answer 1

Answer:

D

Step-by-step explanation:

d. length of a pencil box is not a point

Answer 2

The (d) length of a pencil box cannot be represented by a point.

• In mathematics, a point is a precise spot on a plane that is typically denoted by a dot.
• The dot just serves to identify a point's location.
• A point only has its position on a plane because it is a location, not a thing.
• Points are also used to mark the ends of lines or line segments.

(d) length of a pencil box- correct option

• The length of a pencil box does not represent a point.
• It is a length and not a precise spot on the plane.
• Length is a measure of the distance.
• Hence, this option is the correct choice.

(a) Tip of the needle- incorrect option

• The tip of a needle represents a very precise spot.
• It represents a dot or a point.
• Hence, this option is incorrect.

(b) A vertex of a triangle- incorrect option

• A vertex of a triangle represents a point.
• It indicates a specific location on a plane and is represented by a single capital letter.
• Hence, this option is incorrect.

(c) tip of pen- incorrect option

• The tip of a point also represents a point.
• Hence this is an incorrect option.
