The question, in short
Using AC = 8 cm, BC = 6.5 cm and angle ACB = 38°, construct an accurate drawing of triangle ABC on the given line AC.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Solution · 2 marks
- 1AC is already drawn and is 8 cm long
- 2The given angle is ACB, so it is measured at C
- 3At C, measure 38° from CA and draw a line
- 4From C, draw an arc of radius 6.5 cm to cross that line at B
- 5Join A to B to complete triangle ABC
AnswerAn angle of 38° drawn at C and an arc of 6.5 cm from C fixing B, with AB joined
