Triangle ABC has vertices A left parenthesis negative 1 comma 3 right parenthesis comma space B left parenthesis 3 comma 4 right parenthesis comma space a n d space C left parenthesis negative 1 comma 1 right parenthesis as shown below. stack D E with bar on top is a midsegment of triangle A B C. Find the coordinates of D and E.

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

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.

i think the answer is seven, for if i'm being useless °ω°
