Let's Rotate Mona!
To work this applet...
Note: LARGE POINTS are MOVEABLE.
Make Mona rotate 90 degrees (90 degrees CCW).
1) Where is the point (2,-4) after a rotation of 90 degrees CCW? 2) Where is the point (5,-4) after a rotation of 90 degrees CCW? 3) Write a rotation of 90 degrees CCW as a function. Answer below.
Make Mona rotate 180 degrees (180 degrees CCW).
1) Where is the point (2,-4) after a rotation of 180 degrees CCW? 2) Where is the point (5,-4) after a rotation of 180 degrees CCW? 3) Write a rotation of 180 degrees CCW as a function. Answer below.
Make Mona rotate 270 degrees (270 degrees CCW).
1) Where is the point (2,-4) after a rotation of 270 degrees CCW? 2) Where is the point (5,-4) after a rotation of 270 degrees CCW? 3) Write a rotation of 270 degrees CCW as a function.
Make Mona rotate -90 degrees (90 degrees CW).
1) Where is the point (2,-4) after a rotation of 90 degrees CW? 2) Where is the point (5,-4) after a rotation of 90 degrees CW? 3) Write a rotation of 90 degrees CW as a function. 4) Compare the answers to a 90 degrees CW rotation to the answers to a 270 degrees CCW rotation. What do you notice? Answer below.
Use the function rules from above to answer.
Where would the new points be if A(2,4) V(4,1) E(-3,5) R(4,-2) Y(0,-3) after a rotation 90 degrees counterclockwise? Answer below. Use A', V', E', R' and Y' to indicate the new points.
