Question

please help!

i need some trig help

Answer 1

I'd say any

Answer 2

Well in Geometry there are a few rules to help you find if triangles are similar

There are two which are most important, namely:

AA and SAS rule

So you can tell if two triangles are similar if you have either
AA - angle, angle [ie two angles for each triangle]
SAS - Side, angle, side [ ie two lengths and an angle]

if you have these quantities you can tell if the triangles are similar or not

Hope that's helpful!

Answer 3

A and B would give you the angles which you can use to prove they are similar with the sine rule. and GI is just basic geometry, with HG already being twice TS... GI should also be twice SU

Answer 4

thats what i was thinking, but i wanted to double check, cause i always feel like its a trick question when it gives you the option of all lol.

Answer 5

The rules of sines, are (a/sinA) = (b/sinB) = (c/sinC)

Answer 6

It happens

Answer 7

I agree, I would say all of them

because two of the options provide you with AA rule
and the other gives SAS

all of which are sufficient
