## Challenge #161: Triangles, Triangles, Triangles

17 - Castor

516 on the money.

Sneaky @JoeM  didn't put all the points in a perfect straight line which made for some fun....

Turns out that the create polygon actually takes care of most of the heavy lifting for you - any truly colinear points don't actually correctly resolve into a polygon so you have an easy check.

Looking forward to working through other folk's solutions!

8 - Asteroid

I thought this was going to be way simpler than it turned out to be, that final filter is tricky

7 - Meteor

6 - Meteoroid

15 - Aurora

11 - Bolide

This challenge helped me to learn that spatial point ordering within a triangle influences the outcomes of convex hull versus sequence polygon

Spoiler
the sequence polygon results in three times as many records after using the unique tool, ergo they aren't unique
8 - Asteroid

My solution:

15 - Aurora

Challenge 161 is done!

Took a slightly longer approach

11 - Bolide

This was a fun one, got a full match to the 516 triangles. Keen to see how everyone has implemented logic for colinearity.
