Sammy is classifying quadrilateral EFGH. How can she use coordinate geometry to determine whether EFGH is a parallelogram? E(0,4), F(0,7), G(1,5), H(1, 2)
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.
O Sammy can use the slope formula to show that all sides are equal.

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
