Coplanar lines that do not intersect
Parallel lines

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

4 Different types of angles formed by transversals:
 Corresponding
 Alternate interior
 Alternate Exterior
 Consecutive Interior

2 and 7 are examples of what?
Alternate Interior Angles

2 and 3 are examples of what?
Consecutive Interior Angles

5 and 7 are examples of what?
Corresponding Angles

2 and 4 are examples of what?
Corresponding angles

5 and 8 are examples of what?
Alternate Exterior Angles

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?
You set them equal to each other

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

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

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

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

When trying to explain why something is parallel how would you word it if the angles were:
Alternate Exterior Angles
They are parallel because of the Alternate Exterior Angle Theorm Converse

When trying to explain why something is parallel how would you word it if the angles were:
Corresponding Angles
They are parallel because of the Corresponding Angle Postulate Converse

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

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

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

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

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

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

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

What is true about Vertical Angles and Corresponding angles?
their values are always the same.

A statement made in the ifthen form
Conditional Statement

What is a converse?
When you switch the hypothesis and the conclusion

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