Because an obtuse angle is greater than 90 degrees by definition and a right angle is 90 degrees by definition, so an obtuse triangle would need to have both a right angle and an obtuse angle, which would exceed the number of degrees than a triangle can have, which is 180 degrees.

No an obtuse triangle cant be a right angle because,a right angle is 90 degrees. a obtuse triangle is over 90 degrees
a right triangle and triangles cant have more than one right angle
Because the 3 interior angles of any triangle always add up to 180 degrees. And so it follows that 2 obtuse angles would add up to over 180 degrees.
The three interior angles in a triangle must add up to 180o, and a reflex angle is one that is bigger than 180o. This makes it impossible for a triangle to have any interior reflex angles.
Pythagoras' theorem states that for any right angle triangle its hypotenuse when squared is equal to the sum of its squared sides.
