This was definitely a tricky one! I had to look up collinearity explanations and needed a few hints.

This is a very good exercise. I have learned more than the drawing triangle Thanks @CharlieS. Ideally, this should be in tool mastery blog 🙂

Greetings! Learned to draw triangles and it is very good exercise. 🙂

Key to getting from 540 triangles to 516 was setting a reasonable threshold (<0.00000001) and then checking the degree to which the points on a candidate triangle came to achieving equality in the triangle inequality. (https://en.wikipedia.org/wiki/Triangle_inequality)
