Answer:
(6,3) is the missing 4th vertex.
Explanation:
We know that, a rectangle is made up of 4 sides , 4 vertices and 4 edges.
According to the question, there are 3 vertices marked.
The three vertices are:
IMPORTANT NOTE
If we are measuring the sides of a quadrilateral on a coordinate grid, we have to remember that each and every point comes twice in adjacent sides.
For example:
In the given figure, (-4) and 5 appeared twice in the three given vertices.
Now, we should remove (-4) and 5 from the three vertices.
We will be left with 6 and 3.
So, the 4th point will be the combination of 6 and 3.
Hence, we will get the 4th point as (6,3).
Hope my answer helps you ✌️
