Question

3SpointsWhich is the image of vertex C after the triangle is rotated 180 degrees about the origin?

Answer 1

T' (3,0) A' (5,-1) and C' (2,-4)

1) Considering that the Pre-image coordinates are :T(-3,0), A (-5,1) C(-2,4)

and there was a rotation 180º about the origin, then

2) In the Rotation, the rules for 180º rotation Counterclockwise and clockwise is

Pre-image Image

(x,y) ---- (-x, -y)

3)

Thus,

T' (3,0) A' (5,-1) and C' (2,-4)
