Answer:

Rules of translation and reflection-

When translating a point h units to left, we apply the rule (x, y) → (x-h, y),

When translating a point h units to right, we apply the rule (x, y) → (x+h, y),

When reflecting a point around x-axis, we apply the rule (x, y) → (x, -y),

When reflecting a point around y-axis, we apply the rule (x, y) → (-x, y).

The co-ordinates of the vertices of the ΔABC,

A = (8, 8)

B = (10, 4)

C = (2, 6)

The co-ordinates of the vertices of the ΔA'B'C',

A' = (6, -8)

B' = (8, -4)

C' = (0, -6)

As we can notice that all the x co-ordinates of the vertices are reduced by 2 units and the sign of y co-ordinates are changed. So the triangle was translated 2 units to left, first and then reflected around x axis.
