Answer:
Line 3 is incorrect; we don't know anything about the lengths of HG, FG, HE, and EF, so this line is not valid based on the given information.
Step-by-step explanation:
In the Noah's poof of the construction, segment EG would divide angle FGH into two equal parts, which makes line 2 to be valid. i.e <EGH ≅ <EGF. And it can also be observed that line 4 is a valid theorem in proving the congruent nature of triangles.
But line 3 is not valid because of the condition of the statement. Furthermore, segments FG, EG, HG, HE and FE may not be congruent. Thus, the condition of the statement in line 3 is incorrect.
∠H = ∠J = 27°
∠G = ∠L = 117°
∠F = 180 - (∠H + ∠G) = 180 - (27+117) = 36°
∠K = 180 - (∠J + ∠L ) = 180 - (27+117) = 36°
∴∠F = ∠K = 36°
∴ ΔHGF is similar to ΔJLK
So, the correct statement ⇒ HG and LJ are proportional.
