Given:-
- Vertices of Square , (0,5) , (-1,2) , (-6,0) , (-3,4)
prove :-
- These vertices are a square
⠀ || ☆.Explanation.☆ ||
We Know,
- Square have equal all side .
So, we prove all side are equal are not, if they are equal then we can say these vertices are of a square ,
if they are not equal they we can say these are not vertices are of a square .

Let ABCD be a Square,
Where
- A(0,5) , B(-1,2) , C(-6,0) , D(-3,4)
Using Formula,
★Distance between two vertices = √[(x¹ - x)² - (y¹ - y)²]
Where ,
- (x,y) & (x¹ , y¹) are vertices.

First Calculate AB,
➩ AB = √[(-1-0)² + (2-5)²]
➩ AB = √[(-1)² + (-3)²]
➩ AB = √[1 + 9]
➩ AB = √10.
_________________________
Now, Calculate BC,
➩ BC = √[(-6 + 1)² + (0-2)²]
➩ BC = √[(-5)² + (-2)²]
➩ BC = √(25 + 4)
➩ BC = √29

Now, Calculate CD,
➩ CD = √[(-3 + 6)² + (4-0)²]
➩ CD = √[3² + 4²]
➩ CD = √(9 + 19)
➩ CD = √28

Now, Calculate DA ,
➩ DA = √[(-3-0)² + (4-5)²]
➩ DA = √[(-3)² + (-1)²]
➩ DA = √(9+1)
➩ DA = √10
_________________________
Here,
Distance of all side are unequal .
So, we can say That these are not vertices of a square.
That's Proved.
