Proposition 5: The angles above the base of all triangles that are of two equal sides must be equal: that if its two equal sides are drawn out straight, the two angles beneath the base will likewise be mutually equal.

This paper is not playing nice with my dip pens & after much failure I decided to maybe not be so sentimental about proposition 5 and move on; so three cheers for Wilson Jones transfer letters. 🎉🎉🎉

The failure is just part of the art now.
