Question

writing a two-column proof
given: ∠abc ≅ ∠def and
∠ghi ≅ ∠def
prove: m∠abc = m∠ghi
angles reasons
≅ = ∠abc ∠def ∠ghi m∠abc
m∠ghi
statements reasons

assemble the proof by dragging tiles to
the statements and reasons columns.

Explanation:

Answer:

Statements: $\angle ABC \cong \angle DEF$, $\angle GHI \cong \angle DEF$, $m\angle ABC = m\angle GHI$
Reasons: Given, Given, Transitive Property of Congruence (and Definition of Congruent Angles)
