SESSION 2: The Obtuse Heptagram (Seven-pointed Star).

When it comes to angles, there are the Obtuse and the Acute. Obtuse angles are those that are greater than 90 degrees, and the acute are less than 90 degrees. In the obtuse heptagram, the outer angles are greater than 90 degrees. The angles of the points of the star are also very interesting, in fact the shape of these points are uncannily close to the angles of the Great Pyramid. 

This heptagram has played a pivotal role in both the design of many crop circles, but also in their proportioning. We will look at several crop circles where the obtuse heptagram has proportioned their geometry during this second session.

The Crop Circle at Ludgershall in 2021 (see above) was a beautiful set of nested obtuse heptagrams and is one of the circles we will be drawing in the next session of our course. We hope that by drawing this star and by exploring its many variations, we'll get to know this geometric shape and better understand the ways in which it is expressed in the crop circle phenomenon.  Once we have a good understanding of a shape, we can often go on to learn to identify it in formations past and into the future.  

Building a good geometric vocabulary helps us better understand the crop circles and interpret them. It also helps us understand the building blocks of nature, the creative force; a truly universal language. 

So please join us for the next session on our ongoing course and get up close and personal with this beautiful seven-pointed star!
