a)

b)

a)
To find:
The measure of indicated angle
Approach:
Measuring angles:
The instrument used to measure angles is called a protractor.
For instance, the measure of
To find the degree measure of an angle using protractor:
1. Place the notch of the protractor at the point where the sides of angle meet (the vertex of angle).
2. Place the protractor along a side of the angle so that the scale reads “
3. Using the same (outer) scale, read the angle size by reading the degree measure that corresponds to the second side of the angle.
When “
b)
To find:
The measure of indicated angle
