Explanation:

Step1: Reflect over y-axis: $(x,y)\to(-x,y)$

$Z(0,0)\to Z'(0,0),\ Y(0,4)\to Y'(0,4),\ X(3,4)\to X'(-3,4),\ W(4,-1)\to W'(-4,-1)$

Step2: Reflect over y-axis: $(x,y)\to(-x,y)$

$J(-3,4)\to J'(3,4),\ K(-2,5)\to K'(2,5),\ L(-2,4)\to L'(2,4)$

Step3: Reflect over y-axis: $(x,y)\to(-x,y)$

$K(2,-5)\to K'(-2,-5),\ L(1,0)\to L'(-1,0),\ M(3,-1)\to M'(-3,-1)$

Step4: Reflect over y-axis: $(x,y)\to(-x,y)$

$D(1,-4)\to D'(-1,-4),\ C(0,-3)\to C'(0,-3),\ B(3,-2)\to B'(-3,-2),\ A(5,-3)\to A'(-5,-3)$

Step5: Rotate $180^\circ$: $(x,y)\to(-x,-y)$

$F(1,-1)\to F'(-1,1),\ G(0,4)\to G'(0,-4),\ H(5,3)\to H'(-5,-3),\ I(2,-2)\to I'(-2,2)$

Step6: Rotate $90^\circ$ counterclockwise: $(x,y)\to(-y,x)$

$P(-2,2)\to P'(-2,-2),\ Q(-1,4)\to Q'(-4,-1),\ R(3,3)\to R'(-3,3)$

Step7: Rotate $180^\circ$: $(x,y)\to(-x,-y)$

$K(-5,2)\to K'(5,-2),\ L(-5,5)\to L'(5,-5),\ M(-3,2)\to M'(3,-2)$

Step8: Rotate $180^\circ$: $(x,y)\to(-x,-y)$

$H(1,3)\to H'(-1,-3),\ G(2,5)\to G'(-2,-5),\ F(3,1)\to F'(-3,-1)$

Step9: Rotate $180^\circ$: $(x,y)\to(-x,-y)$

$L(-5,-2)\to L'(5,2),\ K(-4,-2)\to K'(4,2),\ J(-3,-4)\to J'(3,4)$
