Complete the paragraph proof to prove the statement.
Given: ABC DEF and GHI - DEF
Prove: m/ABC = m/GHI
We are given that angle ABC and
are congruent, and that angle GHI and angle DEF
are congruent. By the
the measure of angle ABC is equal to the measure of angle
DEF, and the measure of angle GHI is equal to the measure of angle DEF. By the substitution property, the measure
of angle ABC is equal to
