Angle Relationships Assignment

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 on opposite sides of a transversal but inside the two lines. If the lines are parallel, these angles are equal.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different parallel lines cut by a transversal. If the lines are parallel, these angles are equal.

Front

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles on the same side of the transversal and inside the two lines. If the lines are parallel, these angles are supplementary.

Front

What is the relationship between angles formed by a transversal cutting parallel lines?

Back

When a transversal cuts parallel lines, several angle relationships are formed, including vertical angles, alternate interior angles, corresponding angles, and same-side interior angles.

Front

If angle 4 is 67°, what is the measure of angle 5 if they are same-side interior angles?

Back

Angle 5 is 113° because same-side interior angles are supplementary.

Front

If angle 6 is 120°, what is the measure of angle 2 if the lines are parallel?

Back

Angle 2 is 120° because alternate interior angles are equal.

Front

True or False: If two parallel lines are cut by a transversal, same-side interior angles are equal.

Back

False. Same-side interior angles are supplementary.

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°.

Front

What is the measure of angle 1 if angle 4 is 67° and they are vertical angles?

Back

Angle 1 is 67° because vertical angles are equal.
