Geometric Constructions

The tools to use are a ruler and a pair of compasses.

A few points to remember when doing the types of geometric constructions covered in these lessons:

• Do not use a protractor
• Use a sharp pencil
• Do not erase the construction lines. (They will show the examiner how the lines or shapes were constructed)
