Sammy is classifying quadrilateral EFGH. How can she use coordinate geometry to determine whether EFGH is a rhombus?
E(2,5). F(1.3). G(2.1). H(3.3)

Sammy can use the distance formula to show that the opposite sides have equal slopes.

Sammy can use the distance formula to show that all sides are equal

Sammy can use the slope formula to show that the opposite sides have equal slopes

Sammy can use the slope formula to show that all sides are equal.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
