Any triangle can have a maximum of one right angle. Most right triangles are scalene triangles. The only non-scalene right triangle is a 45° - 45° - 90° isosceles right triangle. It is not possible to have an equilateral right triangle in plane geometry. A scalene triangle does not have to have a right angle, but it can have one.
