Hi everyone !
I've got some trouble...
IJKL is a square and [IJ] is confunded with [BC]
h is the height from A.
C1 is the red square
C2 is the green square
C3 is the blue square
1. How to find IJKL using a and h
2. a< b< c. Classify C1, C2, C3 from the largest.
3. Find ABC triangles (their surface, S) when the square IJKL has the largest surface.
Thank you for your help.
