Higher November 2018 Unit 1 Q2
2. Two straight lines, \(AB\) and \(AC\), are shown below.
The point \(P\) is
- equidistant from line \(AB\) and line \(AC\),
- 6 cm from point \(B\),
- more than 10 cm from point \(A\).
Show clearly the position of point \(P\). [3]

| Scheme | Marks | Comments |
|---|---|---|
| Angle BAC bisected OR Unique point P shown within tolerance of angle bisector | B1 | Allow ± 2° and ± 2mm Accept correct construction or use of protractor. |
| Arc, radius 6 cm, centre B OR Unique point P shown 6 cm (± 2mm) from B | B1 | Of sufficient length to be identified. |
| Correct point P shown. | B1 | Allow F.T. from any previous B0 if equivalent decision required for identifying position of P i.e. an arc, centre B, intersects a straight line drawn from A at two points, with only one of these points over 10 cm from A. A correct point P gains all 3 marks. |
