Parallel Lines Cut by a Transversal

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal.

Front

Define adjacent angles in the context of parallel lines and a transversal.

Back

Adjacent angles are angles that are next to each other and share a common side.

Front

Identify a pair of corresponding angles in a diagram where two parallel lines are cut by a transversal.

Back

∠4 and ∠8 are a pair of corresponding angles.

Front

What notation is used to indicate that two lines are parallel?

Back

The notation used is '∥', for example, \overline{AB} \parallel \overline{HG}.

Front

If m∠TWX = 84°, what is m∠UVY if they are corresponding angles?

Back

m∠UVY = 84°.

Front

What are alternate interior angles?

Back

Alternate interior angles are angles that lie between the two lines and on opposite sides of the transversal.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

Alternate interior angles are equal.

Front

Define vertical angles in the context of intersecting lines.

Back

Vertical angles are the angles opposite each other when two lines intersect, and they are equal.

Front

What is the sum of the angles on a straight line?

Back

The sum of the angles on a straight line is 180°.

Front

How can you determine if two lines are parallel using angle relationships?

Back

If corresponding angles are equal or if alternate interior angles are equal, then the lines are parallel.
