In Delta ABC , AD bot BC and AD^(2)= BD xx CD . Prove that AB^(2) + AC^(2) = (BD + CD)^(2)

In Figure 3, AD _|_BC and BD=1/3CD . Prove that 2 CA^2 = 2 AB^2 + BC^2 .

The perpendicular from A on side BC of a DeltaABC meets BC at D such that DB = 3CD .Prove that 2AB^(2)=2AC^(2)+BC^(2) .

In Delta ABC , AD_|_ BC which intersects BC at D. If BD =3 CD , then prove that 2AB^(2) = 2AC^(2)+BC^(2)

In Delta ABC , BD : CD = 3 : 1 and AD _|_ BC . Prove that 2(AB^(2) - AC^(2)) = BC^(2) .

The perpendicular from A on side BC of a DeltaABC intersects BC at D such the DB = 3 CD . Prove that 2 AB^(2)=2AC^(2)+BC^(2)

In angle ABC , AB=AC and D is a point on BC. If BD = 5cm, AB =12 cm and AD = 8 cm, then the length of CD is: त्रिभुज ABC में, AB=AC है और D, BC पर स्थित एक बिंदु है | यदि BD =5 सेमी, AB = 12 सेमी और AD = 8 सेमी है, तो CD की लंबाई ज्ञात करें |

In a DeltaABC , altitude drawn from vertex A to side BC meets BC at D such that DB=3CD . Prove that 2AB^(2)=2AC^(2)+BC^(2)
