How angles add up!

  1. 1. How Angles Add Up!<br />Angle Addition Postulate<br />
  2. 2. Angle Addition Postulate<br />Add two angles together to create a larger angle. <br />Or subtract a smaller angle from a larger angle to find an angle measure. <br />
  3. 3. Complementary Angles<br />You can identify complementary angles by the two adjacent angles that cover a right angle. The right angle mark is in red to make it easier to identify.<br />
  4. 4. Supplementary Angles<br />Supplementary angles are two angles that sum to 180o. These angles do not have to be adjacent angles. <br />
  5. 5. Linear Pairs <br />Linear pairs are angles that are adjacent and supplementary. They get the name “linear” because these angles create a line. <br />
