A precise angle measurement has high significance in geometry and has various practical applications. Measuring angles with a protractor provides a precise value of angles and helps mathematicians, engineers, and navigators to draw angles on blueprints.
In mathematical terms, an angle is formed when two rays meet each other on a single point. The point on which two rays meet is known as the vertex of the angle. The angles are represented by “∠”.
A protractor is a geometrical tool for measuring angles that helps engineers to precisely measure, and draw them. It is a semi-circular tool marked with degrees 0-180. The degrees on the Protractors are written in two ways i.e. from left to right and right to left. We can measure angles from 0-360 with this tool.
We can find any angle by using a protractor. Let’s know how to use the protractor in easy steps.
Sometimes we can measure an angle without a protractor just looking at it. For example, a straight vertical ray shows 90 degrees, and a straight horizontal rays show 180 degrees. However, for precise measurement of angles, protractors are much needed.
Let’s look at some of the examples of measuring angles using protractors.
Example 1:
Consider we have angle ∠ABC. To find the exact angle, we will follow the above-mentioned steps.
Steps
Thus ∠ABC= 45°
Example 2:
We will look at some more measuring angles examples here.
Consider we have an angle ∠POQ.
To find the measurement of an angle ∠POQ in degrees we will follow these simple steps.
Steps
Thus ∠POQ= 140°
