The figure shows two equilateral triangles with a shared side. Can the triangles ΔIHJ and ΔIKJ be proven congruent?
Question 20 options:
A)
Yes, ΔIHJ ≅ ΔIKJ by AAA.
B)
No, ΔIHJ and ΔIKJ aren't congruent because SSA isn't a congruence theorem.
C)
Yes, ΔIHJ ≅ ΔIKJ by SSS.
D)
There isn't enough information.
