for triangle ABC in A balance. guys that BH is perpendicular to AC. D is the midpoint of BC. On the beam of rays DH took the point M to DM = DH. Proven
a is, triangle BMD = triangle CHD
b, BC is the ray of ABM corner stool
c, suppose x BH HC.so > comparison of two go cs BHD and CHD

For the triangle loss in A = 90 degrees

M point in BC. drawing-MO perpendicular to AB

MK drawing perpendicular to ac. On the beam of rays of OM and KM in turn retrieved 2 points D and E for OM = OD, KM = KE

C/M AD = AE
