How To Use Alternate Exterior Angles to Find the Missing Value of an Angle

The video tutorial covers problem #16, focusing on the properties of parallel lines and transversals. It explains how to identify and understand alternate exterior angles, emphasizing that these angles are equal when a transversal intersects parallel lines. The tutorial concludes with a recommendation for students to review their notes.

What do the arrows on the lines indicate?

• The lines are parallel.

• The lines are intersecting.

• The lines are curved.

• The lines are perpendicular.

What is a transversal?

• A line that is parallel to another line.

• A line that is perpendicular to another line.

• A line that intersects two or more lines.

• A line that curves around another line.

Which of the following describes alternate exterior angles?

• They are supplementary angles.

• They are on the same side of the transversal.

• They are on opposite sides of the transversal.

• They are interior angles.

How are alternate exterior angles related when a transversal intersects parallel lines?

• They are different.

• They are complementary.

• They are supplementary.

• They are equal.

If one alternate exterior angle measures 47 degrees, what is the measure of the other angle?

• 180 degrees

• 90 degrees

• 0 degrees

• 47 degrees
