Concept explainers
To identify: three points that determine the plane M .
Answer to Problem 9CE
B, C and D
Explanation of Solution
Given:
The figure below:
Concept Used:
Postulate 7:
Through any three points there is at least one plane and through any three non-collinear points there is exactly one plane.
By postulate 7, any three non-collinear points on the given plane can be used to determine that plane.
Now observing the given figure, it can be seen that three points that are labeled on the plane M , that are also non-collinear (do not lie on the same straight line) are B, C and D .
So, by using the postulate 7 it can be said that, the points B, C and D can be used to determine the plane M .
