Given that:

m∠YKJ = m∠WJI

m∠WJX = 180

m∠YKZ = 180

m∠KJI = 180

Prove that:

YZ || WX

The following properties may be helpful:

if a = b, then b = a
if m∠ABC = x, then m∠CBA = x
if (m∠WJI = m∠YKJ) and (m∠WJX = 180) and (m∠YKZ = 180) and (m∠IJK = 180), then WX || YZ
if AB || CD, then CD || AB

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.
