Each problem tests your knowledge of the six standard constructions. Identify the correct step, tool use, or construction outcome.

1.

When copying angle DEF to a new vertex V, the construction uses SSS congruence. Fill in the three pairs of congruent sides that make triangles EGH and VJK congruent: EG=‾EG = \underline{\hspace{5em}}, GH=‾GH = \underline{\hspace{5em}}, and EH=‾EH = \underline{\hspace{5em}}.
