2/9 Review - Angle Pairs

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that are on opposite sides of a transversal and outside the two parallel lines. They are equal in measure.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are on the same side of the transversal and in corresponding positions relative to the parallel lines. They are equal in measure.

Front

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

Back

The angles formed have specific relationships: alternate interior angles are equal, alternate exterior angles are equal, and corresponding angles are equal.

Front

How do you identify alternate interior angles in a diagram?

Back

Look for angles that are on opposite sides of the transversal and between the two parallel lines.

How do you identify alternate exterior angles in a diagram?

Back

Look for angles that are on opposite sides of the transversal and outside the two parallel lines.

Front

How do you identify corresponding angles in a diagram?

Back

Look for angles that are on the same side of the transversal and in the same relative position to the parallel lines.

Front

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

Back

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

Front

What is the value of x if angle 1 is 61° and angle 2 is on a straight line with angle 1?

Back

x = 119° (since 180° - 61° = 119°).

Front

If angle 3 is 119° and angle 4 is on the same transversal, what is the relationship between angle 3 and angle 4?

Back

Angle 4 is equal to angle 3 if they are corresponding angles.
