In the figure below, points A, B, C, and F lie on plane P. State the postulate that can be used to show each statement is true.

A. Line AD contains points A and D. 0 00

B. Through any two points¸ there is exactly one line.

C. A line contains at least two points0.

D. If two points lie in a plane¸ then the entire line containing those points lies in that plane.

If two lines intersect¸ then their intersection is exactly one point.

Question 2 (essay worth 10 points) (03.02 mc) in δabc shown below, point a is at (0, 0), point b is at (x2, 0), point c is at (x1, y1), point d is at x sub 1 over 2, y sub 1 over 2, and point e is at the quantity of x sub 1 plus x sub 2 over 2, y sub 1 over 2: triangle abc is shown. point d lies on segment ac and point e lies on segment bc. a segment is drawn between points d and e. point a is at the origin. prove that segment de is parallel to segment ab.
