Re: [Dr. Geo] supplementary angle (defined by 3 points)

[stes]

 

I have a solution (possibly there are different solutions) which I use in :

 

https://github.com/dcstes/wegwijzer

 

This is a repository with a number of Smalltalk sketches (for use in the DrGeo Smalltalk Editor).

 

However my solution uses two angle constructions defined by 3 points:

 

https://github.com/dcstes/wegwijzer/blob/main/stelling-01.st

 

The title text "Nevenhoeken vormen gestrekte hoek" meaning "Supplementary angles form a straight angle".

 

At line 21 and 22 I send two different angle messages with the same summit "S" where angle E and F both form 180 degrees, so E is supplementary to F (or 'nevenhoek' in Dutch).

 

These Smalltalk sketches are not meant as an extension to DrGeo, they are just sketches that I have made using DrGeo.

 

Regards,

David Stes

No, you will have to think about it. You have all you need to make it.

Is it possible to create the supplementary angle (180 degrees - angle) by a method provided by the DrGeoSketch class please ?
