Question

Measure the following angle using a protractor.

  1. 60°
  2. 62°
  3. 65°
  4. 63°

hintHint:

General Angle finding approach using protractor.

The correct answer is: 60°


    * An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
    * The symbol ∠ represents an angle. Angles are measured in degrees (°) using a protractor.
    Given That:
                       
    >>>The angle between the two rays in the figure is determined by knowing the values where the pivots of the rays are rested.
    >>>The first ray is at 0 degrees and then the second ray is at 60 degrees.
    >>>Then, the angle of measurement is 60 degrees.
    >>>Therefore, the angle between the two rays is 60 degrees.

    Step 1:
    We line up one ray with 0°. We then read the angle measurement where the other ray crosses the protractor.
    Step 2:
    Reading from the protractor, the given angle measures 60°.
    >>>Therefore, the angle of measurement is 60 degrees.
