I am so lost an I can't fail this class

11. They are congruent because off of the sides and angles are congruent on both of the polygons which means they are congruent
12. They are congruent because of SAS (Side Angle Side) because segment WX is congruent to segment YZ and angle x is congruent to angle Z and segment XY is congruent to segment ZW
13. Angle 1 = 20° before 180 - 90 - 70 = 20
14. Angle 1 = 55° because 180 -80 - 45 = 55 the angles are congruent in both triangles so you can use the known numbers of one triangle to figure out the other

I hope this helps!
