Front

The two angles that are equal and opposite when two lines intersect are called...

Back

Vertical angles.

Front

A line that intersects two parallel lines is known as a ______________.

Back

Transversal.

Front

If two angles are supplementary, what is the sum of their measures?

Back

180 degrees.

Front

If angle 1 and angle 2 are a linear pair, what is true about their measures?

Back

They add up to 180 degrees.

Front

What do you call angles that are on the same side of the transversal and inside the parallel lines?

Back

Consecutive interior angles.

Front

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

Back

They are equal.

Front

If m∠TWX = 84°, what is m∠UVY if they are corresponding angles?

Back

84°.

Front

If angle 1 = 3x - 4 and angle 3 = 5x - 38, how do you find the measure of angle 4?

Back

Set angle 1 equal to angle 3 and solve for x, then substitute x back to find angle 4.

Front

What is the measure of angle 3 if it is given as 45 degrees?

Back

45 degrees.

Front

If two angles are complementary, what is the relationship between their measures?

Back

Their sum is 90 degrees.
