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

Step-by-step explanation:

The question has missing parameters.

The (missing) given coordinates are:

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:
