Exploring Angles Formed by a Transversal

Miss Backfish introduces angle-pair relationships, focusing on pairs formed at two intersections. She explains corresponding, alternate interior, alternate exterior, same side interior, and same side exterior angles. The video covers how to identify these angles and their properties, including congruence and supplementary relationships when lines are parallel. The tutorial concludes with problem-solving examples using these angle pairs.

Which of the following angle pairs share a common vertex?

• Complementary angles

• Supplementary angles

• Vertical angles

• Alternate interior angles

What is the term for a line that crosses two other lines, forming two distinct intersections?

• Transversal

• Bisector

• Parallel

• Perpendicular

Which angle pair is formed by angles on opposite sides of the transversal but inside the two lines?

• Alternate interior angles

• Corresponding angles

• Alternate exterior angles

• Same side interior angles

Which angle pair is formed by angles on the same side of the transversal and outside the two lines?

• Alternate interior angles

• Vertical angles

• Corresponding angles

• Same side exterior angles

How many pairs of corresponding angles are formed when a transversal crosses two lines?

• Two

• Five

• Three

• Four

Which angle pair is formed by angles in the same relative position at each intersection?

• Alternate exterior angles

• Corresponding angles

• Same side interior angles

• Alternate interior angles

What happens to alternate interior angles when the lines crossed by a transversal are parallel?

• They remain unchanged

• They become complementary

• They become congruent

• They become supplementary

If two lines crossed by a transversal are parallel, what is true about the corresponding angles?

• They are supplementary
