Triangles F G H and F J H share common side F H. Sides F G and G H are congruent. Sides F J and J H are congruent.

Question illustration
A
They are congruent because GH ≅ GF, JF ≅ JH, and FH ≅ FH.
B
They are congruent because opposite sides of a parallelogram are congruent.
C
They are not congruent because only one pair of corresponding sides is congruent.
D
They are not congruent because only two pairs of corresponding sides are congruent.
