Question

prove that points A( 0, 0), B(1,3),C(4,2)and D(3,-1)are the vertices of a square. Also finds its are​

Answer 1

Step-by-step explanation:

All you need to do is find the distance between the four points (adjacent points)

Lets say the square is

A   B

C   D

distance between A and B should be the same as A and C, B and D, C and D

To see if its a square this is the easiest method, find the distance between A and D, then square the distance between A and B, B and D,

Use pythagoras theorem, AB^2 + BD^2 = root of AD
