Question

if triangle abc is isosceles and ad is the altitude from a on bc prove that ad bisects bc

Answer 1

Hello Mate!

Given : ABC is isosceles ∆ where AD is attitude.

To prove : BD = CD.

Proof : In ∆s ABD and ACD we have,

AB = AC [ Given ]

AD = AD [ Common ]

< ADB = < ADC [ 90° each ]

Hence both triangles are congruent by RHS congruency.

Therefore, BD = CD [ c.p.c.t ]

So, AD bisects BC.
