Let X be a point inside rectangle ABCD.  If AX = 3, BX = 3, and CX = 3, then find DX.   

 

                                        AX2 + CX2  =  BX2 + DX2         

 

                                         32  +  32  =  32  +  DX2     

 

                                         DX2  =  32  

 

                                          DX  =  3    

 

 

i copied the following from the internet.  


In Euclidean geometry, the British Flag Theorem says that if a point P is chosen inside a rectangle ABCD, then the sum of the squares of the Euclidean distances from P to two opposite corners of the rectangle equals the sum to the other two opposite corners.
