3.1-3.2 Practice

Front

Which best describes the relationship between angles 7 and 8?

Back

Supplementary Angles: Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If ∠5 ≌∠7, which of the following can be concluded?

Back

r is parallel to s by converse of Alternate Interior Angles Theorem.

Front

What is the angle relationship between the indicated angles in the diagram?

Back

Corresponding Angles: Angles that are in the same position on different parallel lines cut by a transversal.

Front

∠1 and ∠2 are __.

Back

Alternate Exterior Angles: Angles that are on opposite sides of the transversal and outside the two lines.

Front

Which of the angle pairs below is a pair of same-side interior angles?

Back

∠7 and ∠6: Same-side interior angles are on the same side of the transversal and between the two lines.

Front

Define Corresponding Angles.

Back

Corresponding Angles: Angles that occupy the same relative position at each intersection where a straight line crosses two others.

Front

What is the Converse of the Alternate Interior Angles Theorem?

Back

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

Front

What are Same Side Interior Angles?

Back

Same Side Interior Angles: Angles that are on the same side of the transversal and inside the two lines.

Front

Define Vertical Angles.

Back

Vertical Angles: Angles that are opposite each other when two lines intersect. They are always congruent.

Front

What is the definition of Supplementary Angles?

Back

Supplementary Angles: Two angles whose measures add up to 180 degrees.
