Ok I am having issues here. If you are good at math, and are good at writing a proof, then I need your help. The image will show the triangle, and under the triangle, it shows what is given. Now I have to use that to prove that it is an isosceles triangle. I am going to post the person who is grading my proof comments and I have attached my proof. I need help.

"The proof contains many correct elements, but there are errors and missing steps as well. The angles listed in statement 3 are not right angles. Also, CPCTC will be used in this proof, but must be used after triangles are proved congruent."
