Question

The coordinates of a quadrilateral are shown point J (-4.5,3) point K (-1.2,3) point L ( -1.2,8.7) point M (-4.5,8.7). Brenda claims that quadrilateral JKLM is a square

Answer 1

Brenda is wrong

Explanation:

It formed a rectangle

Answer 2

For this case, the first thing we must do is draw the given vertices in the same Cartesian plane.
Then, we join the points.
We observe the resulting figure (see attached image).
Since the sides are of different dimensions, then the quadrilateral is a rectangle.
Answer:
Brenda is wrong.
Quadrilateral JKLM is a rectangle.
