From the shown figure we have:
1) FE = FG ⇒⇒⇒ given
2) ∠EFZ = ∠GFZ ⇒⇒⇒ given
3) FZ = FZ ⇒⇒⇒ Reflexive Property
∴ The triangles are congruent by SAS
The correct choice is:
by SAS only
The SSS postulate or the SAS can be used to prove this. Then the correct option is A.
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In triangle FEZ and FGZ, we have
The triangle FEZ and FGZ are congruent by SAS.
FE = FG (given)
EZ = GZ (given)
∠E = ∠E (given)
The triangle FEZ and FGZ are congruent by SSS.
FE = FG (given)
EZ = GZ (given)
FZ = FZ (common side)
Then the correct option is A.
