Angle Relationships

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.

Front

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

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

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

Define vertical angles.

Back

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

Front

What is the relationship between supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the measure of angle 1 if it is given that angle 1 and angle 2 are complementary and angle 2 measures 56 degrees?

Back

Angle 1 measures 34 degrees, since complementary angles add up to 90 degrees.

Front

What are alternate interior angles?

Back

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

Front

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

Back

The corresponding angle also measures 44 degrees.

Front

What is the relationship between angles formed by two intersecting lines?

Back

The angles formed by two intersecting lines are vertical angles and are equal.

Front

If angle 1 is 27 degrees, what is the measure of angle 4 if angle 1 and angle 4 are alternate exterior angles?

Back

Angle 4 also measures 27 degrees.
