The interior angles in this triangle add up to 180. What is the greatest number of right angles a triangle can contain?Ans: The sum of angles in a triangle is \({180^{\rm{o}}}.\) If the measure of one angle is \({90^{\rm{o}}},\) then the sum of the other two angles will be \({90^{\rm{o}}}.\) This means that the measures of the other two are complementary angles, and they will be less than \({90^{\rm{o}}}\) each. I believe that most of the work here in order to understand this concept and resolve those problems is to let go of your "imaging" brain in a sense, and simply apply the universal algebraic logic to it, as is explained in this video.
