`/_\ABC` is an isosceles triangle with AB=AC. Draw `AP _|_ BC` to show that `/_B=/_C`

Let ABC be an isosceles triangle with BC as its base. Then, rr_(1)=

In an isosceles triangle ABC with AB = AC, D and E are points on BC such that BE = CD (see figure) Show that AD = AE

ABC is a right angled triangle in which /_A = 90^@ and AB = AC . Show that /_B = /_C .

If ABC is an isosceles triangle where B = (1, 3) and C = (-2, 7) then A =

ABC is an isosceles Triangle and angleB=90^@ , then show that AC^2=2AB^2 .

ABC is an isosceles triangle right angled at C. Prove that AB^2=2AC^2 .

triangleABC is an isosceles triangle in which AB = AC. Show angleB=angleC (Hint : Draw APbotBC) (Using RHS congruence rule)

ABC is an isosceles Triangle right angled at C. Prove that AB^2=2AC^2 .
