Taught by Richard Henry, this Geometry Primer workshop is suitable for beginners, or those seeking to refresh their skills.
This is the seventh in a series of ON-LINE Geometry Primer workshops, introducing key geometric principles and ‘starter’ patterns. Each class length is limited to 90 minutes in length. There are 8 Primer sessions in total.
This is the second of two sessions on polygonal constructions, the fundamental starting point of all traditional patterns. This week we will expand our study to examine the heptagon, enneagon, dodecagon and triskedecagon, referencing the work of such key historical geometers as Abu Wafa Al-Buzjani and Leonardo Da Vinci, as well as more recent practitioners. Although this can be taken as a stand-alone workshop, it will build upon the previous workshop Geometry Primer (6) Polygonal Construction Part 1, which can be downloaded from our archive. (Scroll through gallery in banner above to see images of historical designs typical of the patterns that we will examine in this series and former students’ work ).
