*Percent equation - know it: % times whole = part
*Percent of change: find the difference, then divide by the original number, change the decimal to a percent.
*Complementary angles (common man) add up to 90 degrees
*Supplementary angles (super man) add up to 180 degrees
*Constant of proportionality: same thing as slope. The change in y over the change in x.
*Solving inequalities: the only difference is if you multiply or divide by a negative you MUST flip the inequality.
*Unit Rate: comparison of some number to 1 of something else. Miles per hour, price per ounce
*Adjacent Angles: right next to, share 1 side.
*vertical Angles: directly across from each other. Also, equal!
