What is the term for two angles whose sum is 90 degrees?
Complementary angles
What do we call two lines that never intersect, no matter how far they are extended?
Parallel lines
What is the term for two angles whose sum is 180 degrees?
Supplementary angles
What do we call two lines that intersect at a right angle (90 degrees)?
Perpendicular lines
What is the relationship between two lines that are perpendicular to the same line?
They are parallel
Match the following terms with their corresponding definitions:
Complimentary angles = Two angles whose sum is 90 degrees Supplementary angles = Two angles whose sum is 180 degrees Parallel lines = Two lines that never intersect, no matter how far they are extended Perpendicular lines = Two lines that intersect at a right angle (90 degrees)
Match the following terms with their corresponding properties:
Complimentary angles = Add up to 90 degrees Supplementary angles = Add up to 180 degrees Parallel lines = Always have the same slope Perpendicular lines = Have slopes that are negative reciprocals
Match the following terms with their corresponding relationships:
Complimentary angles = Have a sum of 90 degrees Supplementary angles = Have a sum of 180 degrees Parallel lines = Never intersect, no matter how far they are extended Perpendicular lines = Intersect at a right angle (90 degrees)
Match the following terms with their corresponding characteristics:
Complimentary angles = Two angles that add up to 90 degrees Supplementary angles = Two angles that add up to 180 degrees Parallel lines = Two lines with the same slope Perpendicular lines = Two lines that intersect at a right angle
Match the following terms with their corresponding descriptions:
Complimentary angles = Angles that have a sum of 90 degrees Supplementary angles = Angles that have a sum of 180 degrees Parallel lines = Lines that never meet, no matter how far they are extended Perpendicular lines = Lines that intersect at a right angle (90 degrees)
Test your knowledge of basic geometry terms, including angles and lines. Learn about complimentary, supplementary, parallel, and perpendicular concepts. Identify two angles whose sum is 90 or 180 degrees, and recognize lines that never intersect or intersect at a right angle.
