May i know what the constructions things that are in the syllabus? For e.g. angle bisector,perpendicular bisector .....?
yes they are all in the syllabus . Including constructing of a quadrilateral .
Hi,
The syllabus document states the following:
construction of simple geometrical figures from given data (including perpendicular bisectors and angle bisectors) using compasses, ruler, set squares and protractor, where appropriate.
Thanks.

what about incircle of triangle and circumcircle of triangle?
Hi,
Do visit

For the question 23(c) Paper 1 of Nov 2008, the position of the mast M can be found
(1) by using the perpendicular bisectors method of constructing a circum-circle
with centre M
or
(2) by finding the midpoint of the hypotenuse of a right-angle triangle and this
mid-point M is also the centre of the circum-circle
So, to be safe, you should learn them too even they are not stated clearly in the
construction topic of the syllabus.
