    If it had 2 right angles, then it would have 2 ninety degree angles. So those two angles would add to 90+90 = 180 degrees. But there are 3 angles to any triangle and they always add to 180 degrees. If the first two add to 180 degrees, then the 3rd remaining angle must be 0 degrees, which doesn't make much sense.

    So this proves that a triangle cannot have two right angles. Side note: if a triangle does have a right angle, then it is known as a right triangle.
