Transversals

Front

What is a transversal in geometry?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What is the relationship between alternate exterior angles when the lines are parallel?

Back

Alternate exterior angles are congruent when the lines are parallel.

Front

What are alternate interior angles?

Back

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

Front

What is the relationship between alternate interior angles when the lines are parallel?

Back

Alternate interior angles are congruent when the lines are parallel.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position relative to the transversal and the two lines.

Front

What is the relationship between corresponding angles when the lines are parallel?

Back

Corresponding angles are congruent when the lines are parallel.

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

How do you solve for x in an equation involving angles?

Back

You isolate x by using algebraic methods, such as addition, subtraction, multiplication, or division.

Front

What is the definition of vertical angles?

Back

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