In terms of the sides of a triangle, there are three cases: Equilateral: all three sides equal Isosceles: (at least) two sides equal Scalene: no sides equal In terms of the angles, there are also three cases: Right: one right angle, two acute Acute: three acute angles Obtuse: one obtuse, two acute angles Can you see why there are no other possibilities? You can find four of these six types of triangles illustrated in our FAQ on Formulas: http://mathforum.org/dr.math/faq/formulas/faq.triangle.html - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/
