TRANSCRIPT
Rotation: A transformation where a figure is _____________________ around a
fixed _____________ to create a new _______________.
• The lines drawn from the original figure to the __________________ ______
_______________________, and from the center of rotation to the final figure form
the _______________ _______ ____________________.
Label the center of
rotation and the
angle of rotation.
In this unit, we will only rotate _______________________
______________-‐______________ unless otherwise specified!
Draw an arrow going counter clock-‐wise on the clock.
80° clock-‐wise rotation = ________° counter clock-‐wise rotation?

Rotate segment AB 180° when A( , ) and B( , ). Find the coordinates of A’ and B’.
Example!
A’ = ____________________
B’ = ____________________
A( , ) à A’( , )
B( , ) à B’( , )
In other words, 180° rotation:
( , ) à ( , )
200° clock-‐wise rotation = ________° counter clock-‐wise rotation?

Rotate ΔABC 90° when A( , ), B( , ), and C( , ). Find the coordinates of A’, B’ and C’
A’ = ________________
B’ = ________________
C’ = ________________
A( , ) à A’( , )
B( , ) à B’( , )
C( , ) à C’( , )
In other words, 90° rotation:
