Line QR is the hypotenuse of a right-angled triangle QRS and RS is 30º. Complete the construction of the triangle.
Candidates were expected to:
- draw an arc from (R);
- construct and bisect 60º at R;
- construct 60º at Q;
- draw lines at (R) and (Q) to obtain a perpendicular at (S).
The solution is shown below:
