Answer:
R'(-3,-1), S'(-1,-3), T'(-4,'5).
Step-by-step explanation:
Rotations
Rotating a point of coordinates M(h,k) through 180° about the origin maps it to coordinates to M'(-h, -k).
The triangle has the vertices at R(3,1), S(1,3), T(4,5). After a rotation of 180° about the origin it maps to a new triangle with coordinates:
R'(-3,-1), S'(-1,-3), T'(-4,'5).
An image of both triangles is shown below.
