right angled triangle
All angles equal = all sides equal = equilateral. Two angles equal = two sides equal = isosceles. All angles different = all sides different = scalene. An isosceles or scalene triangle may be right-angled or obtuse-angled if one of its angles is a right angle or obtuse angle (respectively).
