Question 15 of 19intermediate🔧 ApplyDiagram5 marks

Draw the angles formed by the following turns in your notebook: 1/2 turn, 1/4 turn, 2/4 turn, 1/6 turn, 4/6 turn, 3/12 turn, 1/2 + 1/4 turn, and 1/8 + 1/6 turn.

Correct Answer

Draw each angle using a protractor or angle measuring tools: 1/2 turn = 180° (straight angle), 1/4 turn = 90° (right angle), 2/4 turn = 180° (straight angle), 1/6 turn = 60° (acute angle), 4/6 turn = 240° (reflex angle), 3/12 turn = 90° (right angle), 1/2 + 1/4 = 3/4 turn = 270° (reflex angle), 1/8 + 1/6 = 7/24 turn ≈\approx 105° (obtuse angle).

Explanation

The chapter provides multiple turn fractions to draw. Learners convert each fraction to degrees (by multiplying by 360°) and draw the corresponding angle.

Solution Steps

  1. Step 1: 1/2 turn = 180° (straight angle)

  2. Step 2: 1/4 turn = 90° (right angle)

  3. Step 3: 2/4 = 1/2 turn = 180° (straight angle)

  4. Step 4: 1/6 turn = 60° (acute angle)

  5. Step 5: 4/6 turn = 240° (reflex angle)

  6. Step 6: 3/12 = 1/4 turn = 90° (right angle)

  7. Step 7: 1/2 + 1/4 = 3/4 turn = 270° (reflex angle)

  8. Step 8: 1/8 + 1/6 = 3/24 + 4/24 = 7/24 turn ≈\approx 105° (obtuse angle)
