We have to keep in mind that if a triangle is a right angled triangle, it is never a obtuse triangle. Because right angled triangle is ##90^0## and sum of a triangle is always ##180^0##. And the sum of remaining two angles must equals to ##90^0##. A obtuse angle is always greater than ##90^0##. So, it is impossible that a right angled triangle also could be a obtuse triangle.
