Congruent angles and parallel lines theorems

Front

What is the Corresponding Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

Front

Define Alternate Interior Angles.

Back

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

Front

What is the relationship between Vertical Angles?

Back

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

Front

What are Alternate Exterior Angles?

Back

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

Front

How can you identify Corresponding Angles in a diagram?

Back

Corresponding angles are located in the same position at each intersection where a transversal crosses two lines.

Front

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

Back

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

Front

What is the relationship between angles formed by two parallel lines and a transversal?

Back

When two parallel lines are cut by a transversal, several pairs of angles are formed, including corresponding angles, alternate interior angles, and alternate exterior angles, which have specific relationships of congruence.

Front

If angle 1 is 44 degrees, what is the measure of its corresponding angle?

Back

The measure of the corresponding angle is also 44 degrees.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

How do you classify angles 1 and 8 if they are on opposite sides of the transversal and outside the parallel lines?

Back

Angles 1 and 8 are classified as Alternate Exterior Angles.
