Line Relationships/Parallel Line Relationships/Proving Lines are Parallel

Coplanar lines that do not intersect

A line that intersects two or more coplanar lines at different points

4 Different types of angles formed by transversals:

2 and 7 are examples of what?

2 and 3 are examples of what?

5 and 7 are examples of what?

2 and 4 are examples of what?

5 and 8 are examples of what?

What do you need to do when you need to find the value of x that makes two lines parallel and the angles are corresponding?

When you  need to explain why to lines are parallel does a Corresponding angle have a theorm or a postulate?

When you  need to explain why to lines are parallel does a Alternate Exterior Angle angle have a theorm or a postulate?

When you  need to explain why to lines are parallel does a Alternate Interior angle have a theorm or a postulate?

When you  need to explain why to lines are parallel does a Consecutive Interior angle have a theorm or a postulate?

When trying to explain why something is parallel how would you word it if the angles were:
Alternate Exterior Angles

When trying to explain why something is parallel how would you word it if the angles were:
Corresponding Angles

Angles that lie outside of the two lines are on opposite sides of the transversal

Angles that lie between the two lines and are on opposite sides of the transversal

Angles that are between the two lines and are on the same side of the transversal

If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent

If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent

If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent

If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary

What is true about Vertical Angles and Corresponding angles?

A statement made in the if-then form

What is a converse?

When do you need to give credit to why the angles are parallel to Angle Addition Postlate?
