You can specify that positive values of angles are measured either clockwise or counterclockwise, and the direction of angle 0 (usually East or North). You can enter angles in grads, radians, or surveyor’s units or in degrees, minutes, and seconds.

## How do you show angles in AutoCAD?

**To Display Angle Information**

- Click Analyze tab Inquiry panel Angle Information. Find.
- Select two lines, or enter p to specify points.
- If you entered p, specify a starting point, a vertex, and an ending point. The results of the calculation are displayed on the command line.

## How do you measure angles?

We measure angles using **a tool called a protractor**. A protractor is half of a circle. A protractor uses units called degrees to measure angles. A protractor can measure angles starting from the left or from the right.

## What is the missing angle?

Help: Since the two angles are supplementary, their sum is 180°. To find the missing angle, **subtract the given angle from 180°**. The result is the missing angle.

## Why do we measure angles?

In the measurement, you will be dealing with the vertex of the angle, which is where the two lines meet to form an angle. Angles are measured in degrees. Measuring angles can make us better prepared to deal with numbers and measurements as well as in tapping into our visual abilities.
