Charles drew a plan for a rectangular piece of material that hehe will use for a blanket. three of the vertices are ( -2.3 and −3.6), (−2.3, and 2.2), and (2.1, and 2.2). what are the coordinates of the fourth vertex?

The coordinates of the fourth vertex is ( 2.1 , -3.6)

Step-by-step explanation:

Given:

The vertices are  ( -2.3 and −3.6), (−2.3, and 2.2), and (2.1, and 2.2).

To Find :

The fourth coordinate = ?

Solution:

Let (a,b) be the missing coordinates

Now let us use the the mid point formula and find the missing coordinate.

Let  ( -2.3 ,−3.6) be the point A

Let  (−2.3,2.2) be the point B

Let   (2.1, 2.2) be the point C

The mid point of AC should be BD

Step 1: Finding The mid pint of AC

The mid pint of AC

Step 2: Lets Equate the midpoints'

The mid pint of BD

=> =  (-0.1, -0.7)

a = 2.1

b = -3.6
