Two statements in a proof are: m∠A = m∠B m∠B = m∠C What reason could you give for the statement m∠A = m∠C? Complete the explanation of your reasoning. You could use either the Property of Equality, since both statements have m∠B in common; or you could use the Substitution Property of Equality by substituting m∠C for in the first statement.
The transitive property states that if a=b and b=c then a=c
so if angle a was equal to 90 degrees and angle b was equal to angle a then angle b is 90 degrees. if angle b is 90 degrees then angle c is 90 degrees and as a result angle a= angle c
