Triangle RST and its image triangle RST are graphed on the coordinate grid below Which Rotation using the origin as the center of rotation transformer RST A a 9 class=

Respuesta :

A) 90 degree clockwise rotation

Answer:

Option A is correct - a 90 degree clockwise rotation

Step-by-step explanation:

Here in the given image, we can assume that RT and corresponding R'T' to be the base of the triangle.

B- a 90 degree counterclockwise rotation - If the figure would have been rotated counterclockwise, the base would have been TS which is not in the corresponding image. So this option is wrong.

C- If it were 45 degrees then the base would have been RS not RT so this is also wrong.

D - this is also wrong as the bases do not match.

Hence, option A is correct.
