u have a picture?
Wondering where the points K, M, and N are located?
yes one picture may be importantly --- i think
Click on "Draw" and sketch it , please.
L is an arbitrary point?
I think you forgot a triangle BCL
so this is like there this ?
I'll try to solve this.
SqueeSpleen --- ATTENTION --- this exersice begin with the word ,,inside a square ..." - so i think that in this way your picture not can being right,correct how do you think ?
Inside... :( I'm horrible with English. I'll make a new draw.
We can Prove Angles are equal all of them it is very easy onlt the figure is complicated
Distances neednot be found
I have a proof using complex numbers but I want a purely geometric proof.
I'm wanting to use trigonometry :p, that's why I'm using distances to figure out the angles.
KM=(1-2(1-cos(30)))CB distance between mid point kn and midpoint nm=KM/2 I forget the parenthesis. the first time.
Take only two adjacent angle and try to proof them equal I have done it Then you can use symetry argument to extend it to all adjacent pairs
Label all points and I shall show you
I'm horrible with geometry but I'll label all points and left it to you. Geometry problems were the problems who gave me the worst times when I was in my countrys maths olympiads :( I named the mid points of the segments after their extrems.
