Triangle ABC has vertices A(2,-4), B(0, 0), C(5,0). Graph and label the vertices of ABCD and
its image A'B'C'D' after reflecting across the line x=1. Choose the correct ordered pairs of the
image A'B'C'.
(2 points)
O A'(0, ), B'(-2, 0), C (4,0)
O A'(0, -4), B (2.0), C'(-4,0)
A'(0,0), B (2, 1), C'(4,1)

Question 2 (essay worth 10 points) (03.02 mc) in δabc shown below, point a is at (0, 0), point b is at (x2, 0), point c is at (x1, y1), point d is at x sub 1 over 2, y sub 1 over 2, and point e is at the quantity of x sub 1 plus x sub 2 over 2, y sub 1 over 2: triangle abc is shown. point d lies on segment ac and point e lies on segment bc. a segment is drawn between points d and e. point a is at the origin. prove that segment de is parallel to segment ab.
