I've got some trouble...
IJKL is a square and B, I, J, C are aligned (alternatively, |IJ| is confounded with |BC|.
h is the height of acute $\triangle$ ABC from A to side BC.
C1 is the red square.
C2 is the green square.
C3 is the blue square
a= |BC|
b= |CA|
c= |AB|
- How to find IJKL using a and h
- a< b< c. Classify C1, C2, C3 from the largest.
- Find ABC triangles (their area, S) when the square IJKL has the largest area.
Thank you in advance.
. I assumed that, e.g., [BC] means the length |BC|? I'm not clear what you mean by [IJ] is *confunded with* [BC]. Do you mean confounded? Or that |IJ| is proportional to |BC|, and varies as |BC| varies? – 2012-11-30
