Name 5 of the 8 sets of supplementary angles

Given:

Parallel lines cut by a transversal.

To find:

The sets of supplementary angles.

Solution:

The reference image is attached below.

Adjacent angles in a straight line are always supplementary.

∠1 and ∠2 are supplementary angles.

∠4 and ∠3 are supplementary angles.

∠5 and ∠6 are supplementary angles.

∠7 and ∠8 are supplementary angles.

∠1 and ∠4 are supplementary angles.

∠2 and ∠3 are supplementary angles.

∠5 and ∠8 are supplementary angles.

∠6 and ∠7 are supplementary angles.

These are the 8 sets of supplementary angles.
