AD is an altitude of an isosceles triangle ABC in which AB = AC. Show that AD bisects BC.

AD is an altitude of an isosceles triangle ABCD which AB=AC. Show that AD bisects angleA

In the fig. traingleABC is an isosceles triangle in which AB=AC and AE bisects angleCAD . Prove that AE||BC

ABC is an isosceles triangle in which AB = AC. AD bisects exterior angle PAC and CD || AB (see Fig. 8.14). Show that (i) angle DAC = angle BCA and (ii) ABCD is a parallelogram.

In Fig., E is a point on side CB produced of an isosceles triangle ABC with AB = AC. If AD bot BC and EF bot AC, prove that triangleABD ~ triangle ECF. .

ABC is an isosceles triangle with AB = AC. Draw AP bot BC to show that angle B = angle C .

ABC is an isosceles triangle with AB=AC draw APbotBC to show that angleB=angleC

ABC is an isosceles triangle with AC = BC. If AB^2 = 2AC^2 , prove that ABC is right triangle.
