Place the protractor’s center point on the vertex of the angle
Align the protractor’s baseline with one side of the angle
Use the correct scale starting from 0 on the aligned side
Read the degree mark where the other side of the angle crosses the protractor
For measuring an angle, record the number in degrees
For drawing an angle, mark the desired degree on the protractor
Draw a line from the vertex through the marked point
Remove the protractor and check the angle if needed
Use the inner scale or outer scale based on the direction of the baseline
Keep the protractor steady while reading or marking
Ensure the protractor is placed flat on the paper
Use a pencil for accurate marking
