Question

Given: ΔABC ≅ ΔEDF

What is the length of rounded to the nearest tenth?



a 1.1
b 3
c 3.2
d 4

Answer 1

length of ...?

Answer 2

sorry line FE

Answer 3

yeah and i think there is still some information mission from the question,
such as a side-length of EDF

Answer 4

no thats all there is
just the picture that is attched and the question that is above

Answer 5

so does ≅ indicates similarity or congruence,

Answer 6

yessss

Answer 7

which one
if you mean similarity ; the problem cannot be solved
if you mean congruence ; the problem can be solved

Answer 8

ok so ≅ means congruence

Answer 9

(the triangles are the same shape (angles) and dimension (lengths)

Answer 10

ok i kno that u have to turn the triangle side ways and line FE match up to line CB so its (3,2) (0,2) and you have to round it to the nearest tenth

Answer 11

and that i dont know how to do

Answer 12

so we just need to find the length of FE which by congruence is exactly the same as length AC

Answer 13

oh i thought it was CB?

Answer 14

the side length in question is the side opposite the right angle
using the Pythagoras theorem
the length AC^2 = length AB^2 + length BC^2

so AC = Sqrt(AB^2+BC^2)

Answer 15

length AB is 1,
length BC is 3,

length AC = sqrt( 1^1 + 3^2)
=sqrt (10)
=3.162

Answer 16

rounding to the nearest tenth ~ 3.2

Answer 17

OMG thank you sooooo freakin muchn(:

Answer 18

do you understand how this works?

Answer 19

yes thank you soo verry much
