Unit 4 Re Test

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary, meaning they add up to 180 degrees.

Front

If m∠12 = 74°, what is m∠4 if they are corresponding angles?

Back

m∠4 = 74° because corresponding angles are equal.

Front

If m∠1 and m∠2 are corresponding angles, what can we say about their measures?

Back

m∠1 = m∠2 because corresponding angles are equal.

Front

If m∠1 and m∠2 are alternate interior angles, what can we say about their measures?

Back

m∠1 = m∠2 because alternate interior angles are equal.

Front

If m∠1 and m∠2 are same-side interior angles, what can we say about their measures?

Back

m∠1 + m∠2 = 180° because same-side interior angles are supplementary.

Front

How do you find the value of X and Y in angle problems?

Back

Use the properties of angles (like corresponding, alternate interior, etc.) and set up equations based on their relationships.

Front

What is the relationship between alternate exterior angles?

Back

Alternate exterior angles are equal when two parallel lines are cut by a transversal.
