hint: similar triangles

little pasture Sep 14, 2024, 2:50 AM

#

i didnt understnad

neon urchin Sep 14, 2024, 2:50 AM

#

have you learnt similar triangles before

little pasture Sep 14, 2024, 2:50 AM

#

i need some through help pls

#

not really

neon urchin Sep 14, 2024, 2:51 AM

#

ok

#

they are triangles with the same proportions, but one can be bigger than the other

little pasture Sep 14, 2024, 2:51 AM

#

ok

neon urchin Sep 14, 2024, 2:52 AM

#

something like this

#

you can prove that two triangles are similar in different ways

little pasture Sep 14, 2024, 2:52 AM

#

yeh yeh now i do

#

i have got the asnwer for this

#

as it is a practice exam

neon urchin Sep 14, 2024, 2:52 AM

#

ok?

little pasture Sep 14, 2024, 2:52 AM

#

but i want to properly understand it

#

thats what i need help with

#

neon urchin Sep 14, 2024, 2:53 AM

#

neon urchin you can prove that two triangles are similar in different ways

have you learnt congruent triangles at least

little pasture Sep 14, 2024, 2:53 AM

#

with the same sides?

#

yes

neon urchin Sep 14, 2024, 2:54 AM

#

little pasture with the same sides?

can you tell me how you would prove two triangles are congruent

little pasture Sep 14, 2024, 2:54 AM

#

using ratios

neon urchin Sep 14, 2024, 2:56 AM

#

what ratios?

little pasture Sep 14, 2024, 2:58 AM

#

as the ones u said like the sides

#

a/a=b/b=c/c

#

they are all the same sides but just the sides have been increased

neon urchin Sep 14, 2024, 3:01 AM

#

ok that’s for similarity

#

you’re right, SSS or PPP (all sides have same ratios) is a good proof of similarity

little pasture Sep 14, 2024, 3:02 AM

#

yes

neon urchin Sep 14, 2024, 3:02 AM

#

the other ones are SAS (two sides and the angle between them) and AA (two equal angles)

little pasture Sep 14, 2024, 3:03 AM

#

holy man

#

i have never been told this once in class

neon urchin Sep 14, 2024, 3:03 AM

#

currently, our side ratios are 5:x-2 and 2x+5:40

little pasture Sep 14, 2024, 3:03 AM

#

yes

neon urchin Sep 14, 2024, 3:04 AM

#

we don’t know if these are equal, so anything with sides in it can’t be used

little pasture Sep 14, 2024, 3:04 AM

#

ohhh ook

neon urchin Sep 14, 2024, 3:04 AM

#

but we can use AA

little pasture Sep 14, 2024, 3:04 AM

#

2 equal lenghts

neon urchin Sep 14, 2024, 3:04 AM

#

two equal angles

little pasture Sep 14, 2024, 3:04 AM

#

ohh sorry

neon urchin Sep 14, 2024, 3:04 AM

#

now we aren’t given any angles either, but we have parallel lines

little pasture Sep 14, 2024, 3:05 AM

#

yes

#

those sides are:ju/jt

#

?

little pasture Sep 14, 2024, 3:23 AM

#

can anyone help me pls

#

neon urchin Sep 14, 2024, 3:52 AM

#

sorry, i was offline

neon urchin Sep 14, 2024, 3:53 AM

#

little pasture those sides are:ju/jt

they’re UT and KL actually

#

you can find equal angles with them

tawdry tusk Sep 14, 2024, 3:57 AM

#

The ratios between similar sides are equal

little pasture Sep 14, 2024, 4:22 AM

#

ohh thats fine

#

i got help from some one else no worries

#help pls with this work i have more work i need to understand and really need help with it
