Measuring Angles worksheets

Download free printable measuring angles worksheets PDF with answers. These worksheets help students practice reading a protractor, measuring acute, obtuse, right, straight, and reflex angles, and drawing angles accurately for grades 4–6.

It is an important skill in geometry that helps us understand the size and direction of turns or corners. Whether you’re working on a school project, designing something, or solving real-world problems, knowing how to measure angles correctly is essential.

To begin, always identify the type of angle you’re dealing with—acute, right, obtuse, or reflex. Recognizing the angle type will help you estimate the measurement before using any tools. This step can save time and improve accuracy.

Next, use a protractor to measure the angle. Place the midpoint of the protractor on the angle’s vertex, and align one side of the angle with the baseline. Then, read the number on the scale where the other side of the angle points. Remember to use the correct scale based on the direction of the angle.

Before using a protractor, students should learn the types of angles and how to name angles correctly. Continue practicing with our types of angles worksheets and naming angles worksheets for complete geometry mastery.

Using a protractor in an anticlockwise direction: 

  1. This is measurement in anticlockwise direction. Thus, we will use the inner scale to measure the angle.
  2. The centre of the protractor is placed on the vertex B of the angle ABC. The base line of the protractor should coincide with the base BC of the angle.
  3. Read the markings where the arm BC overlaps the markings on the protractor. That measurement is the measure of the angle.
  4. Therefore, the angle ABC measures 45°
