    What is the flaw in the student's proof? Justification 4 should be "AB ÷ AD = AB ÷ AC because triangle ABC is similar to triangle ABD." Justification 1 should be "Angle ABC = Angle BCD and Angle BCA = Angle DBC." Justification 2 should be "BC ÷ DC = AC ÷ BC because triangle ABC is similar to triangle BDC." Justification 3 should be "Angle ABC = Angle ADB and Angle BAC = Angle BAD."

    if u set up the angles correctly u will get : Justification 3 should be "Angle ABC = Angle ADB and Angle BAC = Angle BAD."
