Another post to clarify the requirements for the UK GCSE Mathsematics specification. The constructions required are as follows:

**perpendicular bisector of a line segment****constructing a perpendicular to a given line from a given point****constructing a perpendicular to a given line at a given point****bisecting a given angle**

Note that all these Math Open Reference demonstrations are available as a printable atep by step instruction sheet, see for example the **guide to bisecting an angle**.

**Constructing a 60° angle**is required. This is shown here by constructing an equlateral triabgle.

**Math Open Reference**by John Page. (There are many more

**constructions**given on the site which are not a GCSE requirement). Another very useful source for demonstrations comes from

**BBC Bitesize on Loci and Constructions**which gives step by step diagrams and instructions.
