You can print a copy of the graph, stick a pin in the origin, and rotate it 180° to see where the figure ends up.
The origin is the midpoint between each vertex and its image.
Negate every coordinate value, for example, J(-5, -3) gets rotated to J'(5, 3).

Answer:
8 units
Step-by-step explanation:
find the distance of the lines through coordinates given
distance formula:
i) CD=
CD=
CD=4 units
ii) DE=
DE=
DE=
DE= 2 units
iii) ED=
ED=
ED=
ED= 2 units
perimeter of polygon= 2 units+ 2 units+ 4 units
=8 units
