Front

What are alternate interior angles?

Back

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

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

Define consecutive interior angles.

Back

Consecutive interior angles are pairs of angles that are on the same side of the transversal and inside the two lines. They are supplementary when the lines are parallel.

Front

If m∠3 = 97°, what is m∠6 if the lines are parallel?

Back

m∠6 is 97° because alternate interior angles are congruent if the lines are parallel.

Front

How do you solve for x when given two parallel lines cut by a transversal?

Back

You can use the properties of angles formed by the transversal, such as alternate interior angles, corresponding angles, or consecutive interior angles, to set up equations.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180°.

Front

If two angles are supplementary, what is their relationship?

Back

Supplementary angles are two angles whose measures add up to 180°.

Front

What are the properties of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

If m∠1 = 45°, what is m∠2 if ∠1 and ∠2 are vertical angles?

Back

m∠2 is also 45° because vertical angles are congruent.

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.
