HELP WITH 3 QUESTIONS!!! What similarity statement can you write relating the three triangles in the diagram?

OpenStudy (cwrw238):

look at the triangles RTS and RUS

OpenStudy (cwrw238):

they are both right angled triangles can you see any other equal angles?

OpenStudy (cwrw238):

is you can show that there is another pair of equalcorresponding angles in these 2 triangles then they are similar

OpenStudy (cwrw238):

triangle s RTS and RUS are similar because of the 2 right angles and also angle R is common to both

OpenStudy (cwrw238):

can you see why SUT is also similar to the other 2?

OpenStudy (ayyookyndall):

Yes, I can see.

OpenStudy (cwrw238):

OK - in the cae of triangle SUT angle S is the common angle

OpenStudy (ayyookyndall):

Can you help me with 2 more? @cwrw238

OpenStudy (cwrw238):

OK - I'll give you some hints on how to fo them

OpenStudy (cwrw238):

* do

OpenStudy (cwrw238):

oops - angle T was the common angle not S

OpenStudy (cwrw238):

you didn't spot my deliberate mistake!

OpenStudy (ayyookyndall):

Actually I did, but I didnt want to correct you.

OpenStudy (cwrw238):

oh - OK!

OpenStudy (ayyookyndall):

It would be A correct for the problem we did?

OpenStudy (cwrw238):

well 2 angles are given to be equal and also there are 2 opposite angles there ( in the States I think you call them vertical angles).

OpenStudy (cwrw238):

A or B - the order of letters does not matter

OpenStudy (ayyookyndall):

What therom do you think it is?

OpenStudy (cwrw238):

I just noticed - the options are all the same !!

OpenStudy (ayyookyndall):

But only one has to be correct..

OpenStudy (cwrw238):

perhaps they require you to write the triangles so that the equal angles correspond...

OpenStudy (ayyookyndall):

Mhm perhaps..

OpenStudy (ribhu):

i am sure its B
