3.1 Practice and Review

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal.

Front

Which angles are considered vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are parallel lines?

Back

Parallel lines are two lines that run in the same direction and will never intersect, no matter how far they are extended.

Front

Identify the relationship: ∠5 and ∠8.

Back

∠5 and ∠8 are vertical angles.

Front

What is the definition of corresponding angles?

Back

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

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are angles that lie between two parallel lines and on opposite sides of a transversal. They are equal.

Front

How do you identify vertical angles in an intersection?

Back

Vertical angles are formed by two intersecting lines and are located opposite each other.

Front

What is the significance of transversal lines in geometry?

Back

A transversal line intersects two or more lines, creating various angle relationships such as alternate interior, alternate exterior, and corresponding angles.

Front

What is the relationship between alternate exterior angles when lines are parallel?

Back

When two lines are parallel, alternate exterior angles are equal.

Front

What are the properties of corresponding angles when two lines are cut by a transversal?

Back

If the two lines are parallel, corresponding angles are equal.
