Plot AABC on graph paper with vertices A(8,-4), B(8, 1), and C(2,0).
a. What is the area of AABC?
b. AABC is rotated about the origin 180° to become AA'B'C'. Name the coordinates of A', B', and C".
c. This time AABC is rotated 180° about point C to form AA"B" C". Name the coordinates of B".
d. If AABC is rotated 90° clockwise (0) about the origin to form AA""B""C"", what are the coordinates of point A""?
