Question 698526: Carl has a piece of cake in the shape of an isosceles triangle with angles 26 � ,77 � , and 77 �. He wanted to divide it into two equal parts, so he cut it through the middle of the 26 � angle to the midpoint of the opposite side. He says that because he is dividing it at the midpoint of a side, the two pieces are congruent. Is this enough information? Explain. please explain step by step and give a summery for how you got solved the question.
