Transversal Lines

Front

What is a transversal line?

Back

A transversal line is a line that intersects two or more other lines at distinct 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 is the relationship between alternate interior angles when two lines are parallel?

Back

When two lines are parallel, alternate interior angles are congruent.

Front

What are alternate exterior angles?

Back

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

Front

What does it mean for angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If angle 1 and angle 2 are corresponding angles, what can be said about their measures if the lines are parallel?

Back

If the lines are parallel, then angle 1 is congruent to angle 2.

Front

What is the measure of angle 4 if angle 1 = 27° and lines j and k are parallel?

Back

Angle 4 = 27° (since they are corresponding angles).

Front

How do you find the value of x in angle relationships?

Back

Use the relationships between angles (like supplementary or congruent) to set up an equation and solve for x.

Front

What are vertical angles?

Back

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

Front

If angle 3 and angle 4 are supplementary, what is the relationship between them?

Back

The sum of the measures of angle 3 and angle 4 equals 180 degrees.
