Kiran is trying to prove the isosceles triangle theorem. In other words, he wants to prove that Angle ABC = Angle ACB. He first draws triangle ABC such that AB is congruent to AC. He then decides to draw in a line
that goes through A and intersects BC at point D.

a. What is one of the ways Kiran can define this line that he drew that could help
him in his proof?

b. Finish the proof of the isosceles triangle theorem.

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
