Constructions are an integral part of high school Geometry.
Teaching constructions well requires great assessments. You’ll also need a deep knowledge of the construction process, and you’ll want quality construction tools, mainly a compass. Tips for making great constructions are really helpful, as well as having excellent methods for demonstrating the step-by-step procedures.

Now that we know where our students are going, let’s get down to the basics.
In this article, we’re going to look at knowing just how to create those constructions.
Knowledge of the Construction Process
Whether you’re constructing a perpendicular line to a given line through a point not on the line (relatively simple) or constructing a parallel line to a given line through a point not on the line (more involved), brush up on the steps ahead of time!
Practicing the constructions gives you that muscle memory you’ll need when you teach it.
Here, I’m walking you through the steps of the constructions that we teach… in just a quick refresher.
