Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
the coordinates of the vertices are A(1, 4), B(3, 1), C(1, 1), hence
A(1, 4) → A'(1, - 4)
B(3, 1) → B'(3, - 1)
C(1, 1) → C'(1, - 1)
Under a reflection in the line y = - x
a point (x. y) → (- y, - x), hence
A(1, 4) → A'(- 4, - 1)
B(3, 1) → B'(- 1, - 3)
C(1, 1) → C'(- 1, - 1)
