This activity is modified for online learning.
The teacher will give a demonstration of each of the applets before you are given time to explore them.
After watching the demonstration, try this:
1. Move point A to make AB=4.
ABCD will be a 4 x 4 square.
2. Move point E to rest directly above point A.
3. Move the plane to change the size of the cross section, square GHIJ.
