Question

What segments are parallel on the attached diagram?

Answer 1

From the given figure we get,

DC║AB

Explanation:

It is given that,

<DCB and <CBA are supplementary, that means

<DCB + <CBA = 180

If these two angles are on the same side of a traversal CB.

<DCB and CBA are same side interior angles.

CB is the traversal of AB and DC

Therefore we get DC║AB

The correct answer is DC║AB
