Help guys, I’m sure it’s easy for y’all

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

Rule : Rotation center (0,0) , angle of rotation 180° or -180°

Step-by-step explanation:

The vertices of the object and image have coordinates at ;

D(-4,2), D'( 4,-2 ),

E (-1,3), E'( 1,-3 ),

F (-1,-3),F'(1,3),

G (-3,-4),G'( 3,4 ),

You notice that after the rotation ;

( x, y )change to (-x,-y),

This rule is rotation center origin angle 180°

ik this stuph and i am smart donkey

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
