Determine if the following examples depict parallel lines. If the lines are parallel state which theorem proves that they are parallel. If the lines are not parallel state "not parallel".

## Question 1:

1. Are lines j and k parallel? If they are parallel, state which theorem makes them parallel. If they are not parallel, state "not parallel".

## Question 2:

2. Are lines j and k parallel? If they are parallel, state which theorem makes them parallel. If they are not parallel, state "not parallel".

## Question 3:

3. Are lines j and k parallel? If they are parallel, state which theorem makes them parallel. If they are not parallel, state "not parallel".

## Question 4:

4. Which lines are parallel in the diagram above?

## Question 5:

5. Which lines are parallel in the diagram above?
