Introduction to Constructions

David Wees, Andrew Schroth, 2024. aug. 22.

This is a sequence of geometric constructions, each designed as puzzles, where what students figure out how to do in one step can be used in future constructions. I recommend students using Geogebra first and then transferring their constructions (once they have them figured out) to paper using a compass and straightedge.

Given a line segment, draw a circle with its radius as the line segment.
