why are there an infinite amount of planes when there are three points?
because you can rotate the plane on the line in any direction to form an unlimited amount of planes
how many planes contain a given line...why?
infinitely many because a plane can rotate on the line in any direction forming an unlimited amount of planes
suppose two points are in plane P. Explain why the line containing the points is also in plan P
because for every two points there is one line, if two points of a line are in plane P, that means that all of the points of the line and the line are in plane P
if you are given a line segment with A B C, the midpoint is B, what does that tell you about A and C?
that they are the same value
if you are given a midpoint problem with A B and C what do you do to solve it? ( A and C contain variables)
you set AB to equal BC and find the value of the variable and plug it back into both AB and BC then add them together to find the value of AC
what is the segment addition postulate?
if 3 points A B and C are collinear, and B is between A and C, then AB + BC= AC
why are intersecting lines always coplanar?
because 2 points lie on each of the two lines, and if two points of a line are in the plane, then all the points of the line and the line are in the plane
