Initial Diagnostic Audit - Unit F2: Angles and Circles
Section F2.1 - Compass Bearings
1. The diagram below shows the course of a ship's route from A to D.

Point C is directly east of point B.
What is the bearing of

(a)  B from A    °

(b)  C from B    °

(c)  D from C    °

(d)  A from B    °

2. A man has walked 500 m on a bearing of 110°.
Estimate how far east he now is from his starting point.    Distance = m
Section F2.2 - Angles and Circles
3. Calculate the size of the angles α, β and γ in the diagram, where O is the centre of the circle.

(a)  Angle α = °

(b)  Angle β = °

(c)  Angle γ = °

4. Calculate the angle θ in the diagram below where AB is a tangent and O is the centre of the circle.

Angle θ = °

5. Calculate the angle θ in the diagram below where O is the centre of the circle.

Angle θ = °
