Question

Marcia drew a plan for a rectangular piece of material that she will use for a blanket. Three of the vertices are ​(-2.6, -1.5), ( -2.6,3.3), and (2.7, 3.3). What are the coordinates of the fourth​ vertex?

Answer 1

`(2.7,-1.5)`

Explanation:

The points are
`A(-2.6,1.5), B(-2.6,3.3), C(2.7,3.3)`

The fourth vertex will can be found by the points
`A` and
`C`.

The angles between the sides of a rectangle are
`90^(\circ)`.

The
`x` coordinate will be the same as
`C` and the
`y` coordinate will be the same as
`A`. The fourth verex is
`D`.

So, the fourth vertex of the rectangular piece will be
`(2.7,-1.5)`.
