Understanding Vertical Angles

The video tutorial introduces vertical angles, explaining that they are angles across from each other formed by two intersecting lines. It describes how vertical angles are congruent, meaning they have equal measures. The tutorial provides examples, including calculations with specific angle measures, and explains the relationship between vertical and adjacent angles, noting that adjacent angles are supplementary and add up to 180 degrees.

What are vertical angles?

• Angles that are adjacent to each other

• Angles that are across from each other

• Angles that are complementary

• Angles that are supplementary

How are congruent vertical angles represented in a diagram?

• With dashed lines

• With two arcs for each pair

• With one arc for each pair

• With different colors

If one vertical angle measures 120 degrees, what is the measure of its vertical counterpart?

• 60 degrees

• 180 degrees

• 90 degrees

• 120 degrees

What is the sum of angles on a straight line?

• 90 degrees

• 180 degrees

• 120 degrees

• 150 degrees

What is the relationship between adjacent angles?

• They are supplementary

• They are congruent

Which of the following is true about vertical angles?

• They are always equal

• They are always different

• They are always supplementary

• They are always complementary

What do adjacent angles add up to?

• 180 degrees
