How to read these in math books?
3<x<7
I read the above as 3 is less than x is less than 7.
A=B=C
I read the above as A equals B equals C.
Isosceles triangle ABC with AC=BC AF=BG
I read the above as Isosceles triangle ABC with AC being equal to BC, AF being equal to BG
Are my readings acceptable?

Hi 3<x<7 ... does mean that x lies somewhere between three and seven And on your second question If we're referring to the lengths of the sides of an isosceles triangle, two of the sides must be the same (A=B). If the third side turns out to be same (A=B=C) then we'd say it's an equilateral triangle I'm not sure what you mean by F and G there Dave

I know the meanings of the math terms and symbols. I just want to know how to read them in English. Are my readings correct?

dave_anonIf we're referring to the lengths of the sides of an isosceles triangle, two of the sides must be the same (A=B).In this case A, B and C are the vertices, not the sides.

sitifanI know the meanings of the math terms and symbols. I just want to know how to read them in English. Are my readings correct?Yes, but you do not need the word "being" in the last case.

In the US, 3 < x < 7 would be said as: "x is less than 7 and greater than 3", or sometimes this is shortened to: "x is less than 7 greater than 3".
A = B = C would be said as: "A equals B equals C".
For an isosceles triangle, you'd say: "ABC is an isosceles triangle, with AB equal to BC".
For equal line segments, AF and BG, you'd say: "AF is equal to BG", or s

AnonymousIn the US, 3 < x < 7 would be said as: "x is less than 7 and greater than 3",Yes, sorry, actually I do agree that this (or "x is greater than 3 and less than 7") would be more usual when expressing the meaning, as opposed to literally reading out the symbols as written.
