Triangle RST has vertices R(2, 0), S(4, 0), and T(1, –3). The image of triangle RST after a rotation has vertices


R'(0, –2), S'(0, –4), and T'(–3, –1). Which rule describes the transformation?



R0, 90°


R0, 180°


R0, 270°


R0, 360°

Answer:

The correct option is C.

Step-by-step explanation:

It is given that the triangle RST has vertices R(2, 0), S(4, 0), and T(1, –3) and the image has vertices R'(0, –2), S'(0, –4), and T'(–3, –1). .

From the given vertices it is clear that the relation between preimage and image is defined as

\((x,y)\rightarrow (y,-x)\)

This is the rule of rotation, when the figure rotates 90 degree clockwise adn 270 degree counter clock wise.

R0, 270° represents 270 degree rotation counter clock wise about the origin.

Therefore correct option is C.
