Quadrilateral ABCD is graphed on a coordinate plane. Three of its vertices are at A(2.6), Point 8(6.8). and Point (8. 4). Which of the following additional statements is sufficient to prove that quadrilateral ABCD is a square?

0,0

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

27 +27 or 27times 2=54

the diffrence is 0
