Describe fully the single transformation that maps triangle a onto triangle b

Triangle (A) reflected over the line y = x

Step-by-step explanation:

From the figure attached,

Coordinates of the vertices of triangle (A) are A(1, 4), B(1, 2) and C(2, 2)

After transformation of triangle A, coordinates of the vertices A', B' and C' of the image triangle (B) are,

A'(4, 1), B'(2, 1) and C'(2, 2)

Lets choose point A to find the rule of transformation,

A(1, 4) → A'(4, 1)

Rule → (x, y) → (y, x)

It shows triangle (A) has been reflected across a line y = x.

Therefore, triangle (A) maps onto triangle (B) when reflected over the line y = x.
