The Measuring angles exercise appears under the 4th grade (U.S.) Math Mission and High school geometry Math Mission. The objective of this exercise is to learn how to measure angles using a protractor.

Types of problems


1. Measure this angle in degrees - This problem has an angle drawn and a virtual protractor is given. The student is required to measure the angle using the protractor.


  1. The angles in this exercise always end with the number ending with 0.
  2. You can approximate some angles by just looking at them and without using the protractor. Eg: {90^\circ} angles, {10^\circ} angles and {180^\circ} angles.
  3. It is not so easy to get the speed badges in this skill because of the time it takes to drag the protractor towards the angle. But it is easy to get the accuracy badges in it.

Real-life Applications

  1. Measurements are used for many things, such as cooking, and for placing carpet.
  2. Many geometric concepts come up in the fields of architecture and graphical design.
  3. Engineers and architects use angles for designs, roads, buildings and sporting facilities.
  4. Athletes use angles to enhance their performance.
  5. Carpenters use angles to make chairs, tables and sofas.
  6. Artists use their knowledge of angles to sketch portraits and paintings.
