true or false

1) the measurement of an angle can be exposed in degrees and radian

2)an angle is in standard position if the angle has one side on the negative axis

3)two angles in standard position are said to be co terminal if they have common terminal side

4)the reference angle of an angle in standard position is the smallest positive angle between the terminal side

5)the measurement of an angle in standard position is positive if its measured clock wise direction

6)the measurement of an angle in standard position is negative if its measured counter clock wise direction

7)one radian is the measure of the angle subtended by arc whose length is equal to radius of circle​
