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
