Understanding Vertical Angles

The video tutorial explains vertical angles, which are angles opposite each other when two lines intersect. It demonstrates that vertical angles are congruent, meaning they have equal measures. The tutorial provides an example with specific angle measurements to illustrate how to calculate vertical angles and discusses the relationship between adjacent angles, which are supplementary and add up to 180 degrees.

What are vertical angles?

• Angles that are across from each other

• Angles that are adjacent to each other

• Angles that are complementary

• Angles that are supplementary

How are vertical angles related in terms of their measures?

• They are always supplementary

• They are always equal

• They are always complementary

• They are always different

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?

• 150 degrees

• 120 degrees

• 180 degrees

• 90 degrees

What is the relationship between adjacent angles?

• They are supplementary

• They are equal

• They are congruent

• They are complementary

Which of the following is true about vertical angles?

• They are always congruent

• They are always complementary

• They are always adjacent

• They are always supplementary

If two angles are adjacent and one measures 60 degrees, what is the measure of the other angle?

• 180 degrees

• 120 degrees

• 90 degrees

• 60 degrees

What do adjacent angles add up to?

• 120 degrees

• 90 degrees

• 180 degrees

• 150 degrees

Which angles are referred to as 'across the street neighbors'?

• Complementary angles

• Supplementary angles

• Adjacent angles

• Vertical angles

What is the measure of a vertical angle if its adjacent angle measures 60 degrees?

• 90 degrees

• 180 degrees

• 60 degrees

• 120 degrees
