Q2:

Chloe uses a protractor to measure the angle πœƒ , as shown in the diagram. She gets a value of 2 8 ∘ . Which of the following statements explains why this answer is incorrect?

  • AThe resolution of the protractor is 0 . 5 ∘ , so the angle should be measured as 2 7 . 5 ∘ .
  • BThe maximum resolution of the protractor is 1 0 ∘ , so the angle should be measured as 3 0 ∘ .
  • CThe center of the protractor was not placed at the vertex of the two lines that form the angle πœƒ .
