why if there is a triangle ABC, why can't it be written as Triangle CAB

Dear Student,

It can be written. ΔABC ,ΔBCA ,ΔACB,ΔCAB
A triangle can be represented in any of the above mentioned ways but each side's name (A, B & C) should be mentioned; not necessarily in a particular order.
So, 
ΔABC = ΔBCA = ΔACB = ΔCAB
All denote the same thing.

​​​​​​​Regards

Because b is the angle of the triangle.
