Question 2

Which angle is closest to 220°?
Hint: Think about the angle 180° + 45° = 225°

1st diagram shows angle greater than 90 degrees and less than 180 degrees    
2nd diagram shows angle greater than 180 degrees and less than 270 degrees   
3rd diagram shows angle greater than 180 degrees and less than 270 but closer to 270 degrees than diagram 2    
4th diagram shows angle greater than 270 degrees and less than 360 degrees    
  check answer for question 2
