Ok, need some real help.

1)Which undefined terms are needed to define parallel lines? (3 points)

Point, line

Line, plane

Coplanar, line

Point, coplanar

2) A line is an undefined term because it (4 points)

contains an infinite number of points

can be used to create other geometric shapes

describes something that does not have width or depth

is a term that does not have a formal definition

3) Susan wrote the following statements:

Statement 1: If two angles form a linear pair, then they are supplementary angles.

Statement 2: If two lines intersect at one point, then exactly one plane contains both lines.

Which geometry term does each statement represent? (4 points)

Statement 1: theorem; Statement 2: postulate

Statement 1: definition; Statement 2: postulate

Statement 1: theorem; Statement 2: definition.

Statement 1: postulate; Statement 2: theorem

THANK YOU! JUST KNOW YOU'RE A LIFESAVER!!!! :)
