Select the correct answer. Which color type occupies positions on opposite sides of each other in the color whSelect the correct answer from each drop-down menu. In the figure, AB || CD and ∠EIJ ≅ ∠GJI.

Complete the following statements to prove that ∠IKL and ∠JLD are supplementary angles.

It is given that ∠EIJ ≅ ∠GJI.

Also, ∠EIJ ≅ ∠IKL and ∠GJI ≅ ∠JLK, as they are corresponding angles for parallel lines cut by a transversal.

By the definition of congruent angles, m∠EIJ = m∠GJI, m∠EIJ = m∠IKL, and m∠GJI = m∠JLK.

So, m∠IKL = m∠JLK by the
.

Angle JLK and ∠JLD are supplementary angles by the
, so m∠JLK + m∠JLD = 180°.

By the
, m∠IKL + m∠JLD = 180°.

Therefore, ∠IKL and ∠JLD are supplementary angles by definitioneel?
