Triangle

T riangle with three sides and three angles

R eally amazing that it’s a whole branch of math

I sosceles, right, obtuse, equilateral, scalene,

A cute. And then there’s sine, cosine, tangent, and

G ood grief, I’ve left trigonometry back in high school,

E uler and Newton. The numbers don’t add up anymore.
