Let's Create!!!
Instructions:
1. Create points
O=(0,0), P=(1,2), Q=(5,2), and R=(4,4) by using the Input Bar.
2. Showing the label of each points by using Style Bar.
3. Choose the "Name and Value" option when showing the label.
4. Create a triangle PQR by using Polygon Tool.
5. Create slider with the value is angle, the name is a, and the increment is by using Slider Tool.
6. Rotate the triangle PQR to the origin point O(0,0) as center of rotation using the Rotate around Point Tool.
7. Enter a as the angle of rotation and select counterclockwise.
8. Repeat steps 6 and 7, but select clockwise.
9. Explore, consider the coordinates of each point and its shadow, then complete the following table (on the Companion Answer Sheet).Conclusion
Based on your activities and observations in the table above, what is the formula to get the shadow coordinates of a point rotated to the origin point O(0,0) counterclockwise and clockwise? what is the formula to get the shadow coordinates of a point rotated to the origin point O(0,0) counterclockwise and clockwise?
