What are Adjacent Angles?

• Two angles that share a common side and a common vertex but do not overlap.

• Two angles that are opposite each other when two lines intersect.

• Two angles that add up to 90 degrees.

• Two angles whose measures add up to 180 degrees.

• Two angles that are equal in measure.

• Two angles that are adjacent to each other.

What is the relationship between Vertical Angles?

• Vertical angles are supplementary, meaning they add up to 180 degrees.

• Vertical angles are congruent, meaning they have the same measure.

• Vertical angles are complementary, meaning they add up to 90 degrees.

• Vertical angles are always acute angles.

What are Complementary Angles?

How do you identify Complementary Angles?

• Check if the sum of their measures equals 90 degrees.

• Check if the angles are adjacent to each other.

• Check if the angles are both acute.

• Check if the angles are both obtuse.

Can two angles be both Complementary and Supplementary?

• Yes, they can be both at any degree.

• No, two angles cannot be both complementary and supplementary unless they are both 90 degrees.

• Only if one angle is 45 degrees.

• Yes, if they add up to 180 degrees.
