Flashcardizz G-3.2A: Angles and Intersecting Lines

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

Identify the corresponding angles in the following scenario: Two parallel lines cut by a transversal.

Back

Corresponding angles are pairs of angles that are in the same position on the two parallel lines in relation to the transversal. They are equal in measure.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles that lie between the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

What is the relationship between parallel lines and transversals?

Back

When a transversal crosses parallel lines, it creates several pairs of angles that have specific relationships, such as corresponding angles, alternate interior angles, and alternate exterior angles.

Front

If angle 4 is 50 degrees, what is the measure of angle 8 if they are corresponding angles?

Back

Angle 8 is also 50 degrees because corresponding angles are equal.

Front

How do you identify alternate exterior angles in a diagram?

Back

Look for angles that are outside the parallel lines and on opposite sides of the transversal. They will be equal.

Front

What is the sum of the measures of angles on a straight line?

Back

The sum of the measures of angles on a straight line is 180 degrees.

Front

If angle 2 is 70 degrees, what is the measure of angle 6 if they are vertical angles?

Back

Angle 6 is also 70 degrees because vertical angles are equal.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that occupy the same relative position at each intersection where a straight line crosses two others.
