10 The diagram shows the position of point A. Point B is 8 cm from A on a bearing of 062 °. Point C is 6.5 cm from A on a bearing of 194 °. (a) (i) Find and label B and C. Point D is the point on BC that is the shortest distance from A. (ii) Find and label D. (iii) Measure AD. iv) By taking measurements, find the ratio CD : DB. Give your answer in the form 1 : n. (v) The area of triangle ADB is w cm^2. Giving your answer in terms of w, find the area of triangle ADC. (b) The diagram shows the positions of A, E and F. Construct and shade the region inside triangle AEF that is • less than 6 cm from E • nearer to AF than to AE • nearer to A than to F.
