Review measuring angles with a protractor, then try some practice problems.

Measuring angles

Angles are measured in degrees. We can use a protractor to measure how many degrees an angle is.
Example:
Measure the following angle in degrees:
First, we line up the dot on the center of the protractor with the vertex of the angle.
Next, we rotate the protractor so that the 0, degree mark lines up with one side of the angle.
Finally, we read the protractor to see where the other side lines up.
The angle is 70, degree.

Practice

Problem 1
Measure the angle in degrees.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, p, i or 2, slash, 3, space, p, i
