Constructive Geometry with Steve Bass, Part II

Architect and author Steve Bass presents the second part of his Constructive Geometry course, originally taught in-person at the 蜜桃传媒app but made available here in digital format for the first time.

This is the second part of a four-part course. In Part I viewers learn how to draw lines using constructive geometry. The subsequent sections of the course are now available as well: Part III and Part IV.

In this session, viewers will be working with regular polygons: polygons whose sides are all equal, whose internal angles are all equal, and whose points all fall along the same circle.

Physically drawing these geometric constructions will help the viewer to understand these mathematical relationships. Viewers are encouraged to download the accompanying booklet below and actually draw the constructions demonstrated in the video. Only a straightedge and a compass are required to draw the constructions. Rulers, protractors, and triangles are not necessary, though they may be useful for checking one’s work.
