Answer :-
To draw a 50 degree angle with a protactor, proceed as follows :
- Draw a straight line (i.e. an arm of the angle).
- Place a dot at one end of the arm. This dot represents the vertex of the angle.
- Place the centre of the protractor at the vertex dot and the baseline of the protractor along the arm of the angle.
- Find 50 degree angle on the scale and then mark a small dot at the edge of the protractor.
- Join the small dot to the vertex with a ruler to form the second arm of the angle.
- Label the angle with capital letters.
Remember that 50 degree angle cannot be constructed using compass.
