Do You Know Your Triangles?

Which triangle has NO equal sides or angles: the isosceles triangle; the equilateral triangle or the scalene triangle? If you don't know, don't feel bad. No one does--except the people at MathIsFun.com of course.

At MathIsFun, you'll learn (or refresh your failing memory!) that the triangle with 3 equal sides and angles is the equilateral triangle, the one with two equal sides and angles is the hard-to-spell isosceles and the triangle with NO equal sides or angles is called a scalene.

There's more too -- it seems that triangle names can actually indicate what type of angle is inside (who knew?) and that some triangles have two names! Curiouser and curiouser...

OK, that's it for today's Sunday night homework.
