Which tool is best suited for measuring angles?

A protractor is specifically designed to measure angles, making it the best tool for this purpose. It typically has a semicircular or circular shape marked with degrees, allowing users to easily read and determine the angle of a given object or between two lines. This precision makes it essential in fields such as geometry, engineering, and architectural design.

The other tools mentioned serve different measurement needs. A caliper is mainly used for measuring the distance between two opposite sides of an object, a micrometer provides very precise measurements of small dimensions and thicknesses, and a tape measure is generally utilized for measuring lengths and distances rather than angles. Each of these tools has its own specialized functions, but when it comes to angle measurement, the protractor is the clear choice.
