Chapter 11 Math Notes

Angles, Turns and Degrees
When in a fraction, the denominator must be 360!  If it is, the numerator is the measure of the angle in degrees. 






Using a Protractor
Remember, it's important to identify the angle as acute or obtuse before measuring.



Join and Separate Angles 
Finding missing angles is easy if you use what you know: circles are 360 degrees, straight angles are 180 degrees and right angles are 90 degress
