Angle Relationships

Front

What is the definition of Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What is the definition of Corresponding Angles?

Back

Corresponding Angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal.

Front

What is the definition of Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

What is the definition of Vertical Angles?

Back

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

Front

If Angle 2 is equal to 45 degrees, what is Angle 6 equal to and why?

Back

Angle 6 is equal to 45 degrees; they are Corresponding angles.

Front

If Angle 4 is equal to 105 degrees, what is Angle 5 equal to and why?

Back

Angle 5 is equal to 105 degrees; they are Alternate Interior angles.

Front

What angle relationship is shown when two angles are on the same side of the transversal and inside the parallel lines?

Back

The angle relationship is Alternate Interior.

Front

What angle relationship is shown when two angles are on the same side of the transversal and outside the parallel lines?

Back

The angle relationship is Alternate Exterior.

Front

What is the relationship between Angle 1 and Angle 2 if they are on opposite sides of the transversal and outside the parallel lines?

Back

The relationship is Alternate Exterior.

Front

If two angles are corresponding, what can we say about their measures when the lines are parallel?

Back

Their measures are equal.
