To verify:The three points determine a plane.
Answer to Problem 7CE
Three points can determine a plane if and only if the three points are not in one line, i.e. non collinear.
Explanation of Solution
Given information:
The two points determine a line.
Formula used:
A plane contains three points not all in one line
Calculation:
Consider the following statement and give reasoning to state if it is true or false
“Do three points determine a plane?”
From Postulate 5
“A plane contains three points not all in one line.”
Therefore, three points can determine a plane it and only if the three points are not in one line
Hence, the answer is “three points can determine a plane if and only if the three points are not in one line, i.e. non collinear.”
Conclusion:
Three points can determine a plane if and only if the three points are not in one line, i.e. non collinear.
