Prove that ABC is isosceles. State the coordinates of A' B' C', the image of ABC, after a translation 5 units to the right and 5 units down. Prove that quadrilateral AA'C'C is a rhombus. [The use of the set of axes below is optional.]What is the value of the angle marked with x ? x 48 ∘ 3.7 3.7 3.7 3.7. Proof: In order to minimize algebraic complexity, it is very helpful to coordinate the plane in such a way as to make the algebraic arithmetic as easy as possible being careful, of course, to be completely general in the assignment. A common simplification is with one side of a figure being studied along the x -axis and an important point (0, 0 ...
