PROOF IN STEP BY STEP SOLUTION
Step-by-step explanation:
Given : ∠EIJ ≅ ∠IKL and ∠GJI ≅ ∠JLK  they are corresponding angles for parallel lines cut by a transversal.
To Prove : i) if ∠EIJ ≅ ∠GJI, then ∠IKL ≅ ∠JLK
         ii)∠JLK and ∠JLD are supplementary angles i.e.
            m∠JLK + m∠JLD = 180°.
         iii) if ∠IKL ≅ ∠JLK, m∠IKL = m∠JLK.
           Thus m∠IKL + m∠JLD = 180°
Proof: i) we are given that ∠EIJ ≅ ∠IKL and ∠GJI ≅ ∠JLK
       if ∠EIJ ≅ ∠GJI
       ∠GJI ≅∠IKL ( alternate interior angles) (equation 1)
       ∠GJI ≅ ∠JLK (given) (equation 2)
by  equation 1 and equation 2
       ⇒∠IKL ≅ ∠JLK
ii) ∠JLK and ∠JLD are linear pairs and sum of linear pairs are 180°
so  m∠JLK + m∠JLD = 180° i.e. ∠JLK and ∠JLD are supplementary angles.
iii) ∠IKL ≅ ∠JLK ( by i part )
  ∠IKL = ∠JLK  (a)
 ∠JLK + ∠JLD = 180° ( by ii part ) ---(b)
so we can write ∠IKL at place of ∠JLK in (b) by (a)
⇒∠IKL + ∠JLD = 180° i.e. supplementary angles .
