Transversal Angle Relationships

Front

What is a transversal in geometry?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal.

Front

What is the relationship between alternate interior angles?

Back

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

Front

Define vertical angles.

Back

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

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

How do you find the value of 'x' in angle relationships?

Back

You can set up equations based on the relationships between the angles (e.g., corresponding, alternate interior) and solve for 'x'.

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 sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

What is the relationship between same-side interior angles?

Back

Same-side interior angles are supplementary, meaning they add up to 180 degrees when two parallel lines are cut by a transversal.

Front

What is the definition of supplementary angles?

Back

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