In the diagram, if , AG = GD = DH = HB, then which of the following is correct?

I) ΔACG ≅ ΔBEH II) ΔCDE ≅ ΔDEB III) ΔHFB ≅ ΔAFG
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. I and II.
Given that,
Also, AG = GD = DH = HB
According to the given diagram,
CG = EH (Perpendicular distance between two parallel lines)
(I) In triangle ACG and triangle BEH
AG = BH
∠AGC = ∠BHE = 90°
CG = EH
So, ΔACG ≅ ΔBEH by SAS congruency.
(II) In triangle CDE and triangle DEB,
DE = DE (common side)
∠CDE = ∠DEB (corresponding angles)
Let AG = GD = DH = HB = 1
In triangle CDE, CE = GD + DH
⇒ 1 + 1 = 2
In triangle DEB, DB = DH + HB
⇒ 1 + 1 = 2
⇒ CE = DB
So, ΔCDE ≅ ΔDEB by SAS congruency.
(III) No clear relation is given in triangle HFB and triangle AFG.
Hence only I and II are correct.
