4.Cake.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.
