2.1 - 2.2 Parallel, transversals, angles

Front

What are parallel lines?

Back

Lines that never intersect and are always the same distance apart.

Front

Define transversal.

Back

A line that crosses at least two other lines.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two lines.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

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

Back

When a transversal crosses parallel lines, corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.

Front

If angle 1 is 70 degrees, what is the measure of angle 5 if lines are parallel?

Back

Angle 5 is also 70 degrees (corresponding angle).

Front

What is the equation to find the value of x in the context of angles formed by parallel lines and a transversal?

Back

8X - 17 + 5X + 19 = 180.

Front

What are skew lines?

Back

Lines that do not intersect and are not parallel, often found in different planes.
