Final answer:
Supplementary angles are two angles adding up to 180 degrees, typically forming a straight line, while complementary angles add up to 90 degrees, often associated with a right angle.
Step-by-step explanation:
Supplementary angles and complementary angles are both concepts in geometry related to the sums of angles.
Supplementary angles are two angles whose measures add up to 180 degrees. This is the same as the sum of the interior angles of a triangle. An example of supplementary angles would be a pair of angles measuring 110 degrees and 70 degrees; together, they form a straight line.
On the other hand, complementary angles are two angles whose measures add up to 90 degrees. This is usually associated with right angles. An example of complementary angles could be two angles measuring 30 degrees and 60 degrees; together, they make a right angle.
The main difference between supplementary angles and complementary angles is the total sum of their measures; 180 degrees for supplementary and 90 degrees for complementary.
