Answer to question 3

Picture
1) Did the student label the congruent sides with tick marks properly? How do you know?
2) Were the base angles for each respective triangle labeled correctly? How do you know?
3) What is his mistake in triangle ABD? How can this be prevented?
4) How did he get 67 for the base angles in triangle ABC?
Picture
1) Are the lines that the student gave congruent? Explain.
2) Are the lines parallel? Explain.
3) What can the student change to make both of the lines congruent?
Picture
1) How does the student prove that the triangle is Isosceles? What evidence does he give?
2) How does the student attempt to prove that the triangle is a right triangle? What evidence does he give?
3) Do you agree with what he gave for the slopes of AB and AC? Why or why not?
