Transversal Angle Relationships

Front

What are vertical angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What is the relationship between corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

Front

What does it mean for angles to be supplementary?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

If angle 1 is 27 degrees, what is the measure of angle 4 if they are corresponding angles?

Back

Angle 4 is also 27 degrees because corresponding angles are equal.

Front

What is the relationship of angles formed by two intersecting lines?

Back

The angles formed by two intersecting lines are vertical angles and are equal.

Front

What is the definition of transversal in geometry?

Back

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

Front

What are the properties of alternate exterior angles?

Back

Alternate exterior angles are equal when two parallel lines are cut by a transversal.

Front

How do you identify corresponding angles in a transversal situation?

Back

Corresponding angles are located in the same relative position at each intersection of the transversal with the parallel lines.

Front

What is the significance of angle relationships in parallel lines?

Back

Angle relationships help determine the measures of unknown angles when parallel lines are cut by a transversal.
