Standard Position

Finding Terminal Side of Angles Lesson

By Mr. C.

Quadrants in Degrees

• Q1 ( 0 - 90 degrees)

• Q2 (90 - 180 degrees)

• Q3 (180 - 270 degrees)

• Q4 (270 = 360 degrees)

Standard Position

• Initial (Start) is AlWAYS on Positive X- axis

• Terminal (End) is where angle stops

Example 1 - Standard Position

• The green shows the angle from initial side to terminal side

• graph 1  150  degrees   Terminates Q2

• graph 2  210 degrees  Terminates Q3

• graph 3   330 degrees  terminates Q4

Clockwise (Negative Direction)

• The red is the Counter clockwise CCW) positive direction

• The green is  Clockwise (CW) Negative direction

• Every Angle has Both !!

Revolutions -  a 360 degree Turn

• Each Revolution is 360 degrees

• So each time around you must Add 360
