Challenge1: Plot points for ΔCAR in black then plot points for ΔC’A’R’ in blue after a 90° counterclockwise rotation about the point (1,-1). (Hint from notes: move origin?)
Question 9
9.
Challenge2: Plot points for ΔZAG in black then plot points for ΔZ’A’G’ in blue after a 90° counterclockwise rotation about the point(1,2).
What 3 pieces of information do you need to know about the rotation every time you rotate a shape?

Type of Rotation
Order of Rotation
Direction of Rotation
Kind of Rotation
Point of Rotation
A 180° clockwise rotation about the origin will give a different image than a 180° counterclockwise rotation about the origin.
True
False
A 90° clockwise rotation about the origin will give the same image as a 270° counterclockwise rotation about the origin.
True
False
