QuestionAnswer What are complementary angles? Complementary angles are two angles whose measures add up to 90 degrees. What are supplementary angles? Supplementary angles are two angles whose measures add up to 180 degrees. How can you identify if two angles are complementary or supplementary? Check if their measures add up to 90 degrees for complementary angles or 180 degrees for supplementary angles. Can two angles be both complementary and supplementary? No, unless both angles are right angles measuring 90 degrees each, in which case they are both complementary and supplementary. How do you solve problems involving complementary angles on a worksheet? Set up an equation where the sum of the two angles equals 90 degrees and solve for the unknown angle. How do you determine the missing angle in a supplementary pair? Subtract the known angle from 180 degrees to find the measure of the missing angle. What are some common applications of complementary and supplementary angles? They are used in geometry problems, architecture, engineering, and design to ensure angles fit together correctly. 5 Are adjacent angles always supplementary or complementary?
