 Right Angle    

 Acute Angle    

Obtuse Angle

The linear distance between two points on a given lineAngle that measures 90 8

Angle measuring less than90 8 but greater than 0 8Angle measuring greaterthan 90 8 but less than 180 8

 Vertical Angle    

 Linear Pair    

 Complementary Angle    

 Supplementary Angle    

 Adjacent Angle    

Angles opposite each otherwhen two lines cross; vertical angles are equalA pair of adjacent anglesthat form a straight lineThey are supplementaryTwo angles that add up to90 8; They do not have to be adjacent

Two angles that add up to180 8; They do not have to be adjacentTwo angles that have a common side and vertexand do not overlap
