Use protractor to draw angles of: 7 1 2 °

Here, we need to draw an angle 7 1 2 ° by using protractor. 7 1 2 ° can also be written as 7 . 5 ° . To draw an angle 7 . 5 ° using a protractor , proceed as follows Draw a ray AB . Place a dot at B . This dot represents the vertex of the angle. Place the centre of the protractor at B and the baseline of the protractor along the arm AB . Find 7 . 5 ° on the protractor and mark a small dot at the edge of the protractor. Join the vertex B to the small dot with a ruler to form the second arm, BC , of the angle. Label the angle with capital letters ∠ ABC . ∠ ABC = 7 . 5 ° o r 7 1 2 ° is the required angle. Hence, the angle 7 1 2 ° is drawn above using a protractor.

Use protractor to draw angles of: 22 1 2 °

Here, we need to draw an angle 22 1 2 ° by using protractor. 22 1 2 ° can also be written as 22 . 5 ° . To draw an angle 22 . 5 ° using a protractor , proceed as follows Draw a ray AB . Place a dot at B . This dot represents the vertex of the angle. Place the centre of the protractor at B and the baseline of the protractor along the arm AB . Find 22 . 5 ° which is between 22 ° and 23 ° on the protractor and mark a small dot at the edge of the protractor. Join the vertex B to the small dot with a ruler to form the second arm, BC , of the angle. Label the angle with capital letters ∠ ABC . ∠ ABC = 22 . 5 ° o r 22 1 2 ° is the required angle. Hence, the angle 22 1 2 ° is drawn above using a protractor.
