More maths – A little geometry
Let ABC be a direct triangle (you go from A to B to C counterclockwise) in a plane.
D,E,F,G,H five points in the same plane, such that :
-ABDE is an indirect square.
-BCFG is an indirect square.
-BDHG is a direct parallelogram.
Show that AH=CE
and that (AH) and (CE) are orthogonal/perpendicular to each other.
(HA, no more “the answer’s [answer]” and finished… here you have to give proof…)
