Transversal Angles

Front

What are transversal angles?

Back

Transversal angles are angles formed when a transversal intersects two or more lines. They include corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles.

Front

Define corresponding angles.

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines. If the lines are parallel, corresponding angles are equal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. If the lines are parallel, alternate interior angles are equal.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two lines and on opposite sides of a transversal. If the lines are parallel, alternate exterior angles are equal.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie between two lines on the same side of a transversal. If the lines are parallel, consecutive interior angles are supplementary (add up to 180°).

Front

If m∠4 = 40°, what is m∠2 if lines are parallel?

Back

m∠2 = 40° (because ∠2 is corresponding to ∠4).

Front

True or False: ∠14 and ∠10 are alternate exterior angles.

Back

True.

Front

True or False: ∠2 and ∠16 are corresponding angles.

Back

True.

Front

True or False: ∠7 and ∠10 are alternate interior angles.

Back

True.

Front

What are skew lines?

Back

Skew lines are lines that do not intersect and are not parallel. They exist in different planes.
