Angles formed by Parallel lines and Transversal

Front

What are Same Side Interior Angles?

Back

Angles that are inside parallel lines on the same side of the transversal; they are supplementary.

Front

What are Consecutive Interior Angles?

Back

Angles that are on the same side of the transversal and inside the parallel lines.

Front

What is the vertical angle to angle 4 if two parallel lines are cut by a transversal?

Back

Angle 7.

Front

What are Complementary Angles?

Back

Angles that add up to 90°.

Front

Identify the pair of angles that are Alternate Interior Angles: \(\angle7\) and \(\angle2\) or \(\angle3\) and \(\angle8\)?

Back

\(\angle7\) and \(\angle2\) are alternate interior angles.

Front

What are Corresponding Angles?

Back

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

Front

What is the relationship between Alternate Exterior Angles?

Back

They are equal when two parallel lines are cut by a transversal.

Front

Define Transversal in geometry.

Back

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

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect; they are equal.

Front

What is the sum of the angles on a straight line?

Back

180°.
