Question

if two distinct lines intersect, then their intersection is exactly one point. postulate #3: if two distinct planes intersect, then their intersection is a line. postulate #4: if you have three distinct noncollinear points, then there is exactly one plane that contains them. how many noncollinear points are needed to define a plane? 4 2 1 3

Explanation:

Step1: Recall postulate

Postulate #4 states that if you have three distinct non - collinear points, then there is exactly one plane that contains them.

Step2: Determine answer

So, 3 non - collinear points are needed to define a plane.

Answer:

D. 3
