Question

AB BG, AC GC, ZABC LGBC ZBACZBGC

Answer 1

Answer:

Step-by-step explanation:

1) Reflection over $\overline{BC}$

2) The triangles are congruent by SAS, so when $\triangle GBC$ is mapped onto $\triangle ABC$, because points $G$ and $A$ are corresponding, $G'$ will correspond with $A$.

3) Yes, because $\overline{BG} \cong \overline{AB}, \overline{GC} \cong \overline{AC}, \angle BAC \cong \angle BGC$, so the triangles are congruent by SAS.
