Question

A trapezoid has the followingcoordinates Point A) -8,-8, B)-2,2 C) 6,2 D)6,-8. I wantto shrink this shape with a scale factor of K=1/2. Whatare my new coordinates for this Trapezoid?

Answer 1

Determine the new coordinates of the trapezoid.

`A(-8\cdot(1)/(2),-8\cdot(1)/(2))=A(-4,-4)`
`B(-2\cdot(1)/(2),2\cdot(1)/(2))=B(-1,1)`
`C(6\cdot(1)/(2),2\cdot(1)/(2))=C(3,1)`
`D(6\cdot(1)/(2),-8\cdot(1)/(2))=D(3,-4)`

So coordinates of the trapezoid after dilation is,

A(-4,-4)

B(-1,1)

C(3,1)

D(3,-4)
