join A to C2, and B2 and so C, B

ReplyDelete▲AHC2 ≡ ▲CHA2, ▲CFB1 ≡ ▲BFC1, ▲BDA1 ≡ ▲DAB2

( right tr 1) equal radius 2) vertical angles )

HC2 ≡ HA2

DA1 ≡ DB2

FB1 ≡ FC1

HC2 + DA1 + FB1 = HA2 + DB2 + FC1

MC2+MH+DE+EA1+FG+GB1=HG+GA2+MB2+MD+EC1+EF

but MC2=MB2, EA1=EC1, GB1=GA2 ( as tg from a point)

MH + DE + FG = HG + MD + EF
