11. Geometry Questions
1. A point on BC.
Possible answer: D
2. The intersection of plane N and plane T.
Possible answer: BD
3. A plane containing E, D, and B.
Plane T
12. A postulate, or axiom, is a
statement that is accepted as
true without proof. Postulates
about points, lines, and planes
help describe geometric
properties.
