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'?

Respuesta :

Answer:

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).
