Question 5. Sam says a regular polygon with each interior angle 160^° has 18 sides.
Is Sam correct? Show your working and give a reason. [3]External Angles in a Regular Polygon▶ Show worked answerHide worked answer
- M1: exterior angle = 180 - 160 = 20^° (angles on a straight line)
- M1: sides = 360 ÷ 20 (exterior angles sum to 360^°)
- A1: 18, so Sam is correct
Answer: Yes, exterior angle 20^° gives 360 ÷ 20 = 18 sides[3 marks]
