2.In triangle AHF and triangle ABC,
angle ACB= 90^o( angle in semi circle)
angle AFH=180^o -90^o(adj. angle on st. line)
Hence angle ACB=angle AFH
angleHAF = angle BAC (common)
Hence, triangle AHF~triangle ABC
angle ACB= 90^o( angle in semi circle)
angle AFH=180^o -90^o(adj. angle on st. line)
Hence angle ACB=angle AFH
angleHAF = angle BAC (common)
Hence, triangle AHF~triangle ABC
