1. Name the intersection of plane AED and plane HEG.

2. How many planes contain the points A, F, and H?

3. Show that this conjecture is false by finding one counterexample: Two planes always intersect in exactly one line.

Answer 1

1. Intersection is at line EH.

2. 3 planes for each A, F, and H.

3. Planes BFG and ADH do not intersect at all.
