Standard Position all angles in the coordinate plane have their initial side on the x-axis. Positive angles are measured counter-clockwise Negative angle are measured clockwise Give the angle measurements for each of the following: 3 clockwise rotations

2.4 counterclockwise rotations Reference Angle positive, acute angle formed between terminal side and x-axis. In your notes, sketch each angle and indicate the reference angle measure: a.) 150 b.) -315

c.) 225 Quadrantal Angles angles whose terminal side lies on the axes. Coterminal angles angles which differ by 360 and have the same terminal side.

Find 3 coterminal angles to 30 Find 3 coterminal angles to 150 Angle conversion Angles are measures in degrees, minutes and second. A minute is 1/60

of a degree and a second is 1/60 of a minute. (ex. 32 5' 2.34" ) latitude and longitude lines on earth What is the high schools latitude and longitude?

Convert latitude and longitude to just degrees. Angle Conversion: Convert 52.125 to degrees, minutes and seconds.
