Question

Show that the points A(1.2) B(5.4) C (3.8)and D(-1.6) are the vertices of a square ,​

Answer 1

Answer:

it's easy..... just take out the distance between all the four points (using distance formula) if the distance comes same between all the points then we can say that it is a square and for proving the 90' angle you can plot it on graph.

Step-by-step explanation:

distance formula is .....

distance b/w two points =√(X2-X1)^2+ (Y2-Y1)^2
