Answer 1

Could you put the rest of the sentence?

Answer 2

please translate: Legt man ähnliche Dreiecke so übereinander, dass zwei Seiten zusammenfallen, so ist die dritte Seite parallel zur entsprechenden Seite des anderen Dreiecks. Findest du einen Grund dafür?

Answer 3

why are always getting problems in german:)

if you put two similar triangles above each other in a way such that 2 sides are above each other,then the third side of the first triangle is parallel to the third of the second.can you explain why?

Answer 4

can you explain why?

Answer 5

how would the triangles be drawn?

Answer 6

thats only one triangle

Answer 7

right?

Answer 8

if the 2 triangles ABC and AB'C' are similar,why are BC and B'C' parallel,this is the question:)

Answer 9

okay, thanks!

Answer 10

but isn't a also similar?

Answer 11

similar triangles means that the corresponding angles are equal,so <ABC=AB'C'
which means that BC//B'C',corresponding angles..

Answer 12

pardon?

Answer 13

how can you prove 2 lines are parallel?

Answer 14

what are <ABC=AB'C' and BC//B'C' supposed to mean?

Answer 15

<means angle
BC//B'C' means BC parallel to B'C'

Answer 16

okay

Answer 17

so they are parallel because the angles correspond?

Answer 18

since the 2 triangles are similar,then the corresponding angles are equal,so the 2 lines are parallel

Answer 19

sooo...... BC and B'C' are parallel because they have corresponding angles.

Answer 20

is that the right answer?

Answer 21

yes you habe to formulate it in a mathematical way though

Answer 22

oooooh

Answer 23

triangles ABC and AB'C' are similar(given)
=><ABC=<AB'C' (corresponding angles of similar triangles)
=>BC//B'C'(corresponding angles)

that's how i would write it

Answer 24

okay, by the way, what grade did you learn this in?

Answer 25

thanks, you have been a super great help!

Answer 26

welcome

Answer 27

i learned this in grade 9

Answer 28

i think i also have to draw the triangles.... so how would you do that?

Answer 29

ookay.

Answer 30

draw them like i did

Answer 31

okay. so you drew it like one was behind the other?

Answer 32

draw one triangle,then somewhere inside it draw a segment parallel to one side

Answer 33

okay! thank you very very much!
