Be sure to share not just your answer - but if you used a strategy. Happy AEFL(&N) Week!
Thanks for the challenge, Brooke! I have an answer but I'm not very confident in it. I'm guessing I missed a few triangles.
How did you draw all those arrows? Did you use Word? Share your secrets, please because this is a great visual!
I used Google Drawing. I clipped a copy of the original image on my PC using Shift-Windows button-S and pasted it into Google Drawing multiple times.
I like Mark's method as well. Markup on a phone?
I started with all the single triangles. Then I started looking for all the triangles I could make by combining two triangles, then combining three triangles, then four triangles, and finally six triangles.
