Answer 1

Choose an option that would cause the purple-marked angles congruent.

Segment WY is congruent to itself by the reflexive property.

You have two pairs of sides congruent of the two triangles.

Now, you need to get the angles between those sides congruent.

Answer 2

It would be C? WY = WZ.

Answer 3

No, you need a pair of angles with vertex at the point Y.

Answer 4

The angle pairs in the options do not have vertex Y.

So, look for a statement that would cause the angles with vertex Y to be congruent.

Answer 5

What kind of angles are formed if segment WY is perpendicular to segment XZ?
