Statements Reasons

• 1 is a right angle1. given

• 2 is a right angle2. given

• m 1 = 90 3.def of rt angle

• m 2 = 90o4. def of rt angle

• m 1 = m 25. transitive property

• 1  26. def of congruent angles

Statements Reasons

Statements Reasons

statementsreasons

• mAOB = 30o; mBOC = 60o1. given

• mAOB + mBOC = m AOC2. angle add post

• 30o + 60o = m AOC3. substitution

• 90o = m AOC4. simplify

• AOC is a right angle5. def of rt angle
