What is the area of ΔABC?
ΔABC is rotated about the origin 180° to become ΔA′B′C′. Name the coordinates of A′, B′, and C′.
This time ΔABC is rotated 180° about point C to form ΔA″B″C″. Name the coordinates of B″.
If ΔABC is rotated 90° clockwise (↻) about the origin to form ΔA′′′B′′′C′′′, what are the coordinates of point A′′′?
