Question

Use the figure below to answer the question that follows:

What must be given to prove that ΔBJI ~ ΔCJG?

and

∠ BIJ ≅ ∠ CGJ and ∠ JBI ≅ ∠ JIB

and

∠ BIJ ≅ ∠ CGJ and ∠ BJI ≅ ∠ CJG

Answer 1

Only ∠BIJ ≅ ∠CGJ. ∠BJI ≅ ∠CJG, since they both name the same angle and we do not need that to be given to us. This is AA similarity.
