Angle Relationships Practice

What are complementary angles?

• Angles that like each other and give each other compliments
• 
  The angles inside the triangle that are not adjacent to the exterior angle
• 
  Two angles whose sum measures  90 degrees
• 
  Two angles whose sum measures 180 degrees.

What are supplementary angles?

• Two angles whose sum measures 180 degrees
• 
  Two angles whose sum measures  90 degrees
• 
  Two angles in the same position when parallel lines are cut by a transversal
• The angles inside the triangle that are not adjacent to the exterior angle

What are vertical angles?

• The angles inside the triangle that are not adjacent to the exterior angle
• The angles opposite of each other when two lines cross
• The angles inside of a shape
• Two angles whose sum measures  90 degrees

What are alternate exterior angles?

• A pair of angles on the outer side of two lines cut by a transversal, but on opposite sides of the transversal

• The angles opposite of each other when two lines cross

• A pair of angles on the inner side of two lines cut by a transversal, but on opposite sides of the transversal

• Two angles in the same position when parallel lines are cut by a transversal

What are alternate interior angles?

• A pair of angles on the outer side of two lines cut by a transversal, but on opposite sides of the transversal

• The angles opposite of each other when two lines cross

• A pair of angles on the inner side of two lines cut by a transversal, but on opposite sides of the transversal

• Two angles in the same position when parallel lines are cut by a transversal

What is a transversal?

• A line that intersects two or more lines
• The angles opposite of each other when two lines cross
• Two angles whose sum measures 180 degrees
• Lines that intersect to form a 90 degree angle

Find the measure of the angle.

• 10 degrees

• 43 degrees

• 80 degrees

• 37 degrees

Complementary angles always add up to
