angles Flashcards
What are acute angles?
Angles less than 90 degrees
What are right angles?
Angels that are exactly 90 degrees
What are obtuse angles?
Angles greater than 90 degrees and less than 180 degrees
What are straight angles?
Angles that are exactly 180 degrees and are straight lines
What are adjacent angles?
Angles that have a common vertex, they don’t overlap and they’re next to each other
What are vertical angles?
Angles that are non adjacent angles formed by intersecting lines
What are complementary angles?
Two angles with a sum of 90 degrees
What are supplementary angles?
Two angles with a sum of 180 degrees (when they’re adjacent they’re also a linear pair)
What is a linear pair?
Two adjacent supplementary angles
What is an angle bisector?
Ray/segment/line that divides an angle into two congruent angles
