Classifying Triangles

There are many ways to classify triangles. You can classify them by their sides and angles. Here are the ways you do that. First we'll do the sides. Scalene triangles have no equal sides, isosceles have two equal sides, and the equilateral has all equal sides. With the angles, theres the acute triangle with all the angles being under 90 degrees, the right triangle with one right angle, and the obtuse triangle with all angles being over 90 degrees.
