Question

Which transformation could have been applied to Triangle wxy to obtain triangle w'x'y'

Answer 1

Given a triangle WXY with coordinates

`\begin{gathered} W(1,6),X(3,1),Y(1,1) \\ \end{gathered}`

With the image of the transformation W'X'Y' coordinates as

`W^(\prime)(-6,1),X^(\prime)(-1,3),Y(-1,1)`

The transformation rule is

`(x,y)\Rightarrow(-y,x)`

From the transformation rule above, it is observed that the triangle has been rotated 90° counter-clockwise about the origin

The correct option is D
