ConstructionsWhich of the following is a correct method for constructing an angle of 60° at Q?
- A.I only
- B.II only
- C.III only
- D.I and II only
- E.II and III only
Show the answer and explanation
Answer: B (II only)
Explanation
In II, an arc centred at the vertex cuts the line, and an arc of the same radius from that point cuts the first arc; joining gives an equilateral triangle, so 60°. Figure I bisects a right angle (45°).
