Presentation Transcript

• 1 is a right angle 1. given

• 2 is a right angle 2. given

• m 1 = 90 3. def of rt angle

• m 2 = 90o 4. def of rt angle

• m 1 = m 2 5. transitive property

• 1  2 6. def of congruent angles

• mAOB = 30o; mBOC = 60o 1. given

• mAOB + mBOC = m AOC 2. angle add post

• 30o + 60o = m AOC 3. substitution

• 90o = m AOC 4. simplify

• AOC is a right angle 5. def of rt angle
