Given that:

WX || YZ

m∠WXI = 180

m∠YZJ = 180

Prove that:

∠WXZ and ∠XZY are supplementary

The following properties may be helpful:

if (AB || XY) and (m∠ABC = 180) and (m∠XYZ = 180), then AC || XZ
if (WX || YZ) and (m∠WSX = 180) and (m∠YTZ = 180), then ∠WST and ∠STY are supplementary

Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
