A triangle cannot have two right angles. Suppose a triangle had two right angles. Am i right in saying : Then the sum of the two angles would excited 180º And that contradicts the fact the a triangle can only have a sum of angles that is equal to 180º Therefore the triangle can not have two right angles.
