degree | unit of measure for an angle |
ray | part of a line with one endpoint extending indefinitely in one direction |
opposite rays | two rays that have a common endpoint and form a line |
angle | formed by two non-collinear rays that have a common endpoint |
vertex | common endpoint shared by two rays that form an angle |
right angle | measures 90 degrees |

obtuse angle | measures between 90 and 180 degrees |
congruent angles | angles with the same measure |
angle bisector | ray that divides an angle into two equal angles |
adjacent angles | two angles in the same plane that share a common vertex and a common side, but no common interior points |
vertical angles | two nonadjacent angles formed by intersecting lines |
linear pair | adjacent angles whose non-common sides are opposite rays |
