Question

1. What fraction of a full turn is 1°?

2. Name four benchmark angle measurements.

3. What fraction of a whole turn is 45°?

4. What fraction of a whole turn is 90°?

5. What fraction of a whole turn is 30°?

6. What fraction of a whole turn is 60°?

7. if you didn’t have a protractor, how could you reconstruct a quarter turn from 0°
to 90°?

Answer 1

Answer:

1. 1/360

2. degree, radians,

3. 1/8

4. 1/4

5. 1/12

6. 1/6

7. Draw a straight line, take a compass, keep its pin at straight line's beginning, draw a very small semi circle. With same compass length, mark one line on the semi circle i.e. 60° point. From that point, again mark a line on semi circle i.e. 120° point. Mark a straight line from both 60 &120 degree points, where these lines intersect, draw a straight line from beginning of your first straight line through this intersection. This will create a 90° angle. PS :- Excuse my grammar.
