Question

Show that the points (1,7) , (4,2) , (-1,-1)and (-4,4) are the vertices of s square.​

Answer 1

Answer:

Step-by-step explanation:

If the points form a square then all sides and daigonals are equal

Distance formula√(x2-x1)^2+(y2-y1)^2

AB=√34

BC=√34

CD=√34

AD=√34

BD=2√17

AC=2√17

Hence proved that these points form a square
