a)How to Find 180-Degree Angle?

• Draw a straight line which will be the arm of angle.

• Put a dot at one end of the line. ...

• Now place the center of the protractor above the dot or vertex and match the baseline of the protractor along with the arm of the angle.

• Mark the angle 180 degrees with a dot.

b) Here the common point of the angle AOB is O.

Step 2: Count the angle either right side or left side of the protractor from zero degree to 90 degree.

Step 3: name the point at 90 degree as “C. Now Thus we bisect the angle 180 degree as 90 degree.
