ΔFJI is an equilateral Δ:
⇒ All angles are 60º
⇒ ∠IFJ = 60º
----------------------------------------------------------------------
ΔFJI is an equilateral Δ:
⇒ All sides are equal
⇒ FI = FJ = JI
----------------------------------------------------------------------
Since FI is also the side of the square:
⇒ FJ = FG
⇒ ΔGFJ is an isosceles Δ
----------------------------------------------------------------------
Find ∠GFJ:
∠GFJ = ∠GFI+ ∠IFJ
∠GFJ = 90º + 60º = 150º
----------------------------------------------------------------------
Find ∠FJI:
∠FJI = (180 - 150) ÷ 2
∠FJI = 15º
----------------------------------------------------------------------
Answer: ∠FJI = 15º
----------------------------------------------------------------------
