Question

In fig. ABC is a A in which AB = AC and AD is an altitude on BC. Prove that AD bisects LA​

Answer 1

Answer:

proof- angle BAD= angle CAD

given - BDA=CDA = 90 ( AD altitude)

AB=AC (isosceles triangle)

therefore angle B=angle C

consider triangle ABD and CAD

angleB=angleC (A)

angleBDA = angleCDA. (A)

AD = AD (S)

By AAS property ABD congruent to ACD

by cpct BAD=CAD

hence proved
