Question

A triangle's coordinates are (-2,1), (-6,1), and (-4, 5). After the triangle is rotated clockwise 270°about the origin, what are the new coordinates?

Answer 1

well, the initial x coordinates become the -y coordinates, the y coordinates become the +x
example (-4, 5) becomes (5,4)

Answer 2

the triangle starts out in Quad IV , and ends up in Quad III

try a test point to see what happens

the x's become y's , and the y's become negative x's

Answer 3

bob, did you rotate far enough?
