Semester Midterm Review Topic 1-3

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal. They are equal in measure.

Front

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are Same-Side Interior Angles?

Back

Angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary (add up to 180 degrees).

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

What is the Law of Detachment?

Back

If p→q is a true statement and p is true, then q must also be true.

Front

What is the Law of Syllogism?

Back

If p→q and q→r are true statements, then p→r is also a true statement.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

How do you find the measure of an angle using Corresponding Angles?

Back

If two parallel lines are cut by a transversal, the corresponding angles are equal.

Front

How do you find the measure of an angle using Alternate Interior Angles?

Back

If two parallel lines are cut by a transversal, the alternate interior angles are equal.

Front

What is the relationship between Same-Side Interior Angles?

Back

If two parallel lines are cut by a transversal, the same-side interior angles are supplementary.
