Which of the following statements is needed within this proof?
given: kite defc; zcde = zefc
prove: egf - acgd

The requires statement is second option

∠ CDG ≅ ∠ EFG  

Step-by-step explanation:

Given:

Kite DEFC

∠ CDE ≅ ∠ EFC

To Prove:

Δ EGF ~ Δ CGD

Proof:

In Δ CGD and Δ EGF

∠ CDG ≅ ∠ EFG  {Requirement}

∠ CGD ≅ ∠ EGF  {Vertically opposite angles are equal}

∴ Δ CGD ~ Δ EGF { by A-A similarity test}

i.e Δ EGF ~ Δ CGD Proved
