GEO 4.2 Transversal Angles Classwork

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal. They are equal in measure.

Front

Define alternate interior angles.

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie between two parallel lines on the same side of a transversal. They are supplementary, meaning they add up to 180 degrees.

Front

What is the relationship between vertical angles?

Back

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

Front

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

Back

The 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 inside the two parallel lines.

Front

What is the sum of same-side interior angles?

Back

The sum of same-side interior angles is 180 degrees.

Front

If angle 3 is 70 degrees, what is the measure of angle 7 if they are corresponding angles?

Back

Angle 7 is also 70 degrees because corresponding angles are equal.

Front

If angle 4 is 110 degrees, what is the measure of angle 6 if they are alternate interior angles?

Back

Angle 6 is also 110 degrees because alternate interior angles are equal.
