## THIS USER ASKED 👇

**When the coordinates (1, 1), (7, 3), (8, 0), and (2, −2) are joined, which shape is formed?**

## THIS IS THE BEST ANSWER 👇

A rectangle states that a parallelogram has all its interior angles at right angles ie, 90 degrees and opposite sides are equal.

In view of the coordinates

A (1, 1), B (7, 3), C (8, 0) and D (2, -2)

Using a Slope Formula:

Calculate the slope of each pair:

For A (1, 1) and B (7, 3)

By definition of slope;

The same,

For B (7, 3) and C (8, 0)

For C (8, 0) and D (2, -2)

For D (2, -2) and A (1,1)

you can see:

Slope AB = Slope Slope of the CD

and

Slope BC = Slope DA

As well as that;

Similarly, the slope product of each pair of side rows is perpendicular (ie 90 degrees).

Then by definition a Rectangle;

when the coordinates (1, 1), (7, 3), (8, 0), and (2, −2) are then joined, the rectangle shape is created.
