Question

writing a two-column proof
given: ∠abc ≅ ∠def and
∠ghi ≅ ∠def
prove: m∠abc = m∠ghi
assemble the proof by dragging tiles to
the statements and reasons columns.

Explanation:

Answer:

Statements:

1. $\angle ABC \cong \angle DEF$, $\angle GHI \cong \angle DEF$
2. $m\angle ABC = m\angle DEF$, $m\angle GHI = m\angle DEF$
3. $m\angle ABC = m\angle GHI$

Reasons:

1. Given
2. Definition of congruent angles
3. Transitive property of equality
