A triangle has vertices at R (1, 1), S (-2,-4), and T (-3,-3). The triangle is transformed according

are the coordinates of S'?

A. (-4,2)

Step-by-step explanation:

We are given that,

The vertices of the triangle are rotated about the origin by 270° counter-clockwise.

This transformation changes the co-ordinate (x, y) to (y,-x).

Thus, we get,

Vertices New vertices after 270° rotation

R = (1,1) R' = (1,-1)

S = (-2,-4) S' = (-4,2)

T = (-3,-3) T' = (-3,3)

Thus, the co-ordinate of S' are (-4,2).
