ADJACENT ANGLES

• angles that share a side and a vertex.
• lying near, close, or contiguous;
• just before, after, or facing
• supporting or being an ally of a group or subculture without being a part of it

COMPLEMENTARY

• have measures that add to 30°
• have measures that add to 90°
• have measures that add to 180°
• have measures that add to 360°

PARALLEL

• the same distance apart, never touching
• involving the simultaneous performance of operations
• a person or thing that is similar to another
• occurring at the same time or in a similar way;

PERPENDICULAR

• cross to form a 90° angle
• the same distance apart, never touching
• A point where two or more rays or the arms of an angle meet
• two angles that add to 180°

RIGHT ANGLE

• an angle that measures 0°

VERTICAL ANGLES
