In exercises 27-30, three vertices of DEFG are given. Find the coordinates of the remaining vertices: D(-2,-4), F(0,7), G(1,0)

Step-by-step explanation:

Given

Parallelogram: DEFG

Required

Find the coordinates of

To do this, we make use of mid-point formula which is:

This gives:

Multiply through by 2

By comparison:

and

So, we have:

and

and

This gives:

and

Hence, the 4th coordinate is:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
