Question

State whether each object represents a point, line or plane,
1. Stretched electric wire:
2. Book cover, :
3. Tip of a needle
4. Edge of a ruler:
5. Wall​

Answer 1

1. Stretched electric wire - a line
2. Book cover - a place
3. Tip of a niddle - a point
4. Edge of a ruler - a line
5. Wall - a place

Step-by-step explanation:

• Stretched electric wire represents a line because when its thickness is neglected, it can be extended in both sides infinitely.

• Book cover represents a plane because its surface is flat and can be extended infinitely.

• Tip of a needle represents a point because it has no dimension or zero dimension having no length or width.

• Edge of a ruler represents a line because it is similar to any straight line drawn on paper.

• Wall represents a plane because it is flat with two dimensions. However its surface is either rough or smooth.
