Question

the perpendicular from a to the base BC at D such that BD is equal to 3 CD prove that 2 a b square is equal to 2 AC square + BC square​

Answer 1

... BC at D such that DB= 3CD .prove that 2AB square =2AC ... 9CD2 = 8(BC/4)2 [Since, BC = DB + CD = 3CD + CD = 4CD] ... Let BD = 3y , CD = y, and thus BC = 4y.
