Once upon a time, Mr. and Mrs. Triangle had triplets. As you can imagine, they were very excited about their babies! But deciding what to name them was harder than they imagined.
this delightful tale of how the Triangle Triplets got their names will solidly teach mathematicians of all ages the di erences between Equilateral, Scalene, and Isosceles triangles. Never again will you have to wonder which is which!
