Front

What is the measure of angle 1 if it is given that m∠1 = 131°?

Back

m∠1 = 131°.

Front

What are angles that lie on opposite sides of the transversal and outside of the parallel lines called?

Back

Alternate Exterior Angles.

Front

Identify a line that is skew to line FG.

Back

Line DC is skew to line FG.

Front

If x + 2 = 6, solve for x.

Back

x = 4.

Front

What are angles that lie on the same side of the transversal and in corresponding positions called?

Back

Corresponding Angles.

Front

Define Alternate Interior Angles.

Back

Angles that lie between the two parallel lines and on opposite sides of the transversal.

Front

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

Back

The sum is 180°.

Front

If two lines are cut by a transversal and the alternate interior angles are equal, what can be concluded about the lines?

Back

The lines are parallel.

Front

What is the definition of Vertical Angles?

Back

Angles that are opposite each other when two lines intersect.

Front

If m∠A = 49° and m∠B is a corresponding angle, what is m∠B?

Back

m∠B = 49° (since corresponding angles are equal).
