Parallel lines & transversals

Front

A line that passes through 2 or more lines is called a ______________.

Back

transversal

Front

What is the relationship between ∠1 and ∠4 if they are formed by two parallel lines cut by a transversal?

Back

Vertical Angles

Front

Find the value of x if the angles formed by the transversal are such that ∠3 + ∠4 = 180° and ∠3 = x.

Back

x = 133

Front

In the diagram, which of the following statements are false? ∠1 and ∠4 are vertical angles, ∠4 and ∠5 are alternate interior angles, ∠1 and ∠8 are alternate interior angles, ∠2 and ∠6 are corresponding angles.

Back

∠1 and ∠8 are alternate interior angles

Front

What is the measure of ∠2 if it is corresponding to ∠6 which measures 38°?

Back

142°

Front

Define corresponding angles in the context of parallel lines and a transversal.

Back

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

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between the two lines and on opposite sides of the transversal.

Front

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

Back

Alternate exterior angles are equal.

Front

What is the sum of the interior angles formed by a transversal intersecting two parallel lines?

Back

The sum is 180°.

Front

If ∠5 = 58°, what is the measure of ∠3 if ∠3 and ∠5 are alternate interior angles?

Back

∠3 = 58°.
