Exercise Name: Name angles
Math Missions: 4th grade (U.S.) Math Mission, 7th grade (U.S.) Math Mission
Types of Problems: 4

Name angles is an exercise under the 4th grade (U.S.) Math Mission and 7th grade (U.S.) Math Mission. This exercise practices the naming process of angles.

Types of Problems

There are four types of problems in this exercise:

  1. Another name: This problem refers to an angle in a picture and asks the user to select another correct way of naming the particular angle.

    Another name

  2. Numbered angle: This problem asks the user to identify which number is the label of a given named angle.

    Numbered angle

  3. Select names: This problem has a diagram drawn and the user multiple selects all the correct names of the angle.

    Select names

  4. Word problems: This problem describes a situation, often on a clock, and asks the user to name the angle that would complete the problem.

    Word problems


This exercise is easy to get accuracy badges but is medium to get speed badges because there are many places where the user needs to be patient and methodical or they may answer incorrectly.

  1. The word problems seems to be generally clock problems.
  2. There seem to be three answers to the select names problem.
  3. In most (but not all) cases the select names problem can be done by looking at the vertex, and using that angle and the two names with that vertex in the middle.
  4. If there are more than three answers on select names with the vertex in the middle, look for the two answers that reverse the beginning and last letters (in addition to the vertex by itself).

Real-life Applications

  1. Engineers and architects use angles for designs, roads, buildings and sporting facilities.
  2. Athletes use angles to enhance their performance.
  3. Carpenters use angles to make chairs, tables and sofas.
  4. Artists use their knowledge of angles to sketch portraits and paintings.
