REASONING

Supply a valid conclusion for the given hypothesis: If  $\overrightarrow{OM}$  bisects  $\angle$  LON, then 

•  $\angle$  LOM  $\cong$   $\angle$  NOM

•  $\angle$  LOM  $\cong$   $\angle$  LON

•  $\angle$  MON  $\cong$   $\angle$  NOL

• no valid conclusion can be made

The method of proof by contradiction is:

• Direct Proof

• Formal Proof

• Indirect Proof

• Two Column Proof

If m $\angle$  R + m  $\angle$  M = 90 $\degree$  , then 

•  $\angle$  R  $\cong$   $\angle$  M

•  $\angle$  R and  $\angle$  M are right angles

•  $\angle$  R and  $\angle$  M are complementary

•  $\angle$  R and  $\angle$  M are supplementary

The If-then form of the statement "Parallel lines never intersects" is:

• If two lines intersect, then they are parallel.

• If two lines are parallel, then they never intersect.

• If two lines are not parallel, then they intersect.

• If two lines intersect, then they are not parallel.
