More Geometry Lessons
In these lessons, we will learn how to use a pair of compasses and a straight-edge to construct different geometric shapes given certain conditions.
Geometric constructions involve drawing geometric shapes that satisfy certain requirements using a straight-edge and a pair of compasses.
The tools to use are a ruler (or straight-edge) and a pair of compasses.
A few points to remember when doing the types of geometric constructions covered in these lessons:
The following diagram shows some examples of constructions. Scroll down the page for more examples and solutions.
