Degrees and turns

Mathematics · Geometry · conceptual

Know that angles are measured in degrees, where one degree is 1/360 of a full turn; understand that an angle turning through n one-degree angles has a measure of n degrees

What mastery looks like

  • Explain that a full turn is 360° and a right angle is 90°
  • Describe what 'one degree' means in terms of a fraction of a circle
  • State that an angle of 45° has turned through 45 one-degree angles

Check your understanding

If Degrees and turns knows a full circle is 360 degrees, can they tell you how many degrees a quarter turn is — and explain roughly what one single degree looks like?
