Question

Construct triangle ABC, in which AB = 6cm, angle BAC = 96° and angle ABC = 35°.

Measure the length of BC.
Give your answer to 1 d.p.

Answer 1

BC = 7.9 cm

Explanation:

To construct triangle ABC:

• Draw a line 6 cm long. Label one endpoint A and the other endpoint B.

• Measure an angle of 96° from point A of AB in an anticlockwise direction. Draw a line.

• Measure an angle of 35° from point B of AB in a clockwise direction. Draw a line.

• The point of intersection of the two lines is point C of the triangle.

• Measure the length of BC. BC = 7.9 cm.
