Transversals

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

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.

Front

What are vertical angles?

Back

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

Front

What is the relationship between consecutive interior angles?

Back

Consecutive interior angles are supplementary, meaning their measures add up to 180 degrees.

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

The corresponding angles are congruent.

Front

If m∠1 = 70°, what is m∠2 if ∠1 and ∠2 are vertical angles?

Back

m∠2 = 70° because vertical angles are congruent.

Front

If m∠3 = 110°, what is m∠4 if ∠3 and ∠4 are alternate interior angles?

Back

m∠4 = 110° because alternate interior angles are congruent.

Front

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

Back

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

Front

If two angles are supplementary, what is the relationship between their measures?

Back

The sum of their measures is 180 degrees.
