Respuesta :

The coordinates of the quadrilateral

A(5,6)

B(10,6)

C(8,1)

D(3,1)

Part A.

The rule for a rotation counterclockwise of 180°

[tex](x,y)\rightarrow(-x,-y)[/tex]

A'=(-5,-6)

B'=(-10,-6)

C'=(-8,-1)

D'=(-3,-1)

Then we will draw the quadrilateral

the original is the red

and the rotate is the blue

Part B

the coordinate change as the given rule seen previously for rotation of 180° counterclockwise

[tex](x,y)\rightarrow(-x,-y)[/tex]
