For drawing angles using a protractor, we’ll need a pencil and a ruler. And simply observe the following steps:
Step 1: Draw a base line with the ruler.
Step 2: Mark the point on the base line where the vertex will be located.
Step 3: Put the protractor on the base line and make sure its centre point is exactly on the vertex.
Step 4: Starting from zero, follow the curve of the protractor until you get to the size of the angle you need. Put a mark at this point.
Step 5: Use you ruler and join this marked point and the vertex in a straight line. This line will give you the required angle.
