Exploring Angle Pair Relationships

What defines adjacent angles?

• Angles that are opposite to each other

• Angles that add up to 180 degrees

• Angles that share a common vertex and a common side

• Angles that add up to 90 degrees

What is true about vertical angles?

• They are always complementary

• They are always supplementary

• They share a common side

• They are congruent

Which angles are formed by intersecting lines?

• Vertical angles

• Supplementary angles

• Adjacent angles

• Complementary angles

What does it mean when angles are congruent?

• They are complementary

• They are supplementary

• They have the same size and shape

• They add up to 180 degrees

How can complementary angles be identified?

• Their sum is 90 degrees

• They are adjacent to each other

• They form a straight angle

• Their sum is 180 degrees

How can you remember the sum of complementary angles?

• Turn the 'C' into an 8 for 180 degrees

• Turn the 'C' into a 9 for 90 degrees

• By remembering they are always adjacent

• By remembering they form a straight line

How many angles can form a complementary set?

• Only two angles

• Two or more angles

• Exactly three angles

• One or two angles

What sum do supplementary angles have?

• 180 degrees

• 90 degrees

What is a characteristic of supplementary angles?

• They always form a right angle

• They are always congruent

• They sum up to 90 degrees

• They can be adjacent or non-adjacent

What is the sum of the angles in a straight angle?

• 180 degrees

• 90 degrees

• 360 degrees

• 45 degrees
