Drawing A Rotation
We are going to "draw" the 140o counter clockwise rotation of Triangle ABC around the origin.
Rotate point A
1. Using the segment tool draw a segment from Point A to the origin.
- Using settings make the segment a grey -------- segment.
- Using settings make the segment a grey -------- segment.
- When using the distance tool after clicking the icon select the endpoints of the segment you woud like to measure.
- What do you notice about the length of these segments?
- Go to the left side of the screen and start to check off the circles (so it is NOT colored in) of the commands so you ONLY see Triangle ABC and Point A'.
- Select (click) Triangle ABC, then Origin, then tpye in 140 and make sure counter clockwise is checked
- Check to see if the rotated image MAPS onto your rotated A', B', and C' points.
