Answer 2

5. Next time include the entire page in the photo. I'm guessing it's U at the top right and O at the bottom right.

First box.

SE ≅ SU

Given

Second box

angle 1 ≅ angle 2

Those are vertical angles, which are always congruent

Third box

angle E = angle U

Given

Next box, three arrows in.

triangle MES ≅ triangle OUS

Angle - Side - Angle

Last box:

MS ≅ SO

Corresponding parts of congruent triangles.

6.

First box:

angle E ≅ angle U

Given

Second box:

NS ≅ NS

reflexivity (aka it's the same segment)

Third box:

angle 1 = angle 2

Definition of angle bisector

Next box:

triangle WNS ≅ triangle ENS

Angle - Side - Angle

Next:

WN ≅ EN

Corresponding parts of congruent triangles.
