are you sure there are no typoes in the question especially below line : `Which pair of triangles is similar?`

OpenStudy (domebotnos):

I'm looking...

OpenStudy (domebotnos):

No typoes. Why?

OpenStudy (domebotnos):

But it is asking which choice has triangles that are similar? :/

ganeshie8 (ganeshie8):

Hey no wait

ganeshie8 (ganeshie8):

we don't know whether angle C is 90 or not so you can eliminate all options that have triangle CDE

ganeshie8 (ganeshie8):

that leaves you with only one correct option !

OpenStudy (domebotnos):

How do we know that angles ABE and EBC are forty-five degrees?

ganeshie8 (ganeshie8):

thats a good question, they need not be 45 degrees
