Week 6 Flashcard - Angles, Parallel Lines & a Transversal

Front

What are 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 alternate interior angles when two parallel lines are cut by a transversal?

Back

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

Front

Define corresponding angles in the context of parallel lines and a transversal.

Back

Corresponding angles are the angles that are in the same position at each intersection where a transversal crosses two parallel lines. They are equal.

Front

What type of angles are formed when two lines intersect?

Back

When two lines intersect, they form vertical angles and adjacent angles.

Front

What are adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

How can you identify alternate exterior angles?

Back

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

Front

What is the sum of the interior angles on the same side of a transversal?

Back

The sum of the interior angles on the same side of a transversal is supplementary, meaning they add up to 180 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 determine if two lines are parallel using angles?

Back

If a transversal creates equal alternate interior angles or equal corresponding angles, the lines are parallel.

Front

What are the properties of corresponding angles?

Back

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