Question

what is the use of compass?
a tool used to draw a circle.
a tool used to draw angles.
a tool used to draw straight lines and measure distances.
a tool used to write measurements.

Explanation:

A compass in geometry (Mathematics - Geometry subfield) is a tool specifically designed to draw circles or arcs. The second option is incorrect as protractors are used for angles. The third option describes a ruler or straightedge with measurement, and the fourth is not a compass's function. So the correct description is the first option.

Answer:

A. A tool used to draw a circle.
