We are given coordinates of triangle △JKL are J(3,4) K(3,1) L(1,1) and
△J’K’L’ are J’(-3,-5) K’(-3,-2) L’(-1,-2).
We know, rotate a figure about 180° about the origin, (x,y) would result (-x,-y).
So, we can "Rotate 180° about the origin." first.
After rotating 180° about the origin, J(3,4) K(3,1) L(1,1) points would transform to new coordinates J(-3,-4) K(-3,-1) L(-1,-1).
If we move 1 unit down. So the new coordinate of (-x,-y) would become (-x, -y-1).
J(-3,-4) K(-3,-1) L(-1,-1) coordinates would transform to J(-3,-4-1) K(-3,-1-1) L(-1,-1-1).
And those are coordinates exactly J’(-3,-5) K’(-3,-2) L’(-1,-2).
Those are the given coordinates of transformed triangle △J’K’L’.
So, the steps of transformations can be summarize
First step : Rotation of 180 degrees about the origin.
Second step: Translation 1 unit down.
