P3: Properties of Parallel lines

Front

What are corresponding angles?

Back

Angles that are in the same position on parallel lines in relation to a transversal. For example, if two parallel lines are crossed by a transversal, the angles in matching corners are corresponding angles.

Front

What is the value of y if angle 2 is 58 degrees and angle 6 is y?

Back

y = 29 degrees (since angle 2 and angle 6 are corresponding angles).

Front

Which angle is NOT congruent to angle 5?

Back

Angle 6 is NOT congruent to angle 5.

Front

What is the relationship between vertical angles?

Back

Vertical angles are angles that are opposite each other when two lines cross. They are always congruent.

Front

If angle 5 is 65 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle is also 65 degrees.

Front

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are congruent.

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 degrees.

Front

If angle 1 is 110 degrees, what is the measure of angle 3 if they are corresponding angles?

Back

Angle 3 is also 110 degrees.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal. They are congruent.

Front

If angle 4 is 60 degrees, what is the measure of angle 8 if they are alternate interior angles?

Back

Angle 8 is also 60 degrees.
