Congruence transformations are:
A ) Translating,
B ) Reflecting,
C ) Rotating.
The midpoint of (x1,y1) and (x2,y2) is

just average them
(4,1) and (-2,4)
the midpoint is

(1,-1.5)
The angles are congruent because they are vertical so we can set them equal to one another.
3x + 50 = 6x - 10
3x + 60 = 6x
60 = 3x
20 = x
