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.

ABC is an isosceles triangle with AB = AC.Take a trace-copy of ABC and also name it as ABC. Is angleB = angleC ? Why or why not?

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 and D is a point on an BC such that ADbotBC to prove that angleBAD=angleCAD ,

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 an isosceles triangle ABC with AB = AC, D and E are points on BC such that BE = CD (see Fig. 7.29). Show that AD = AE.

ABC is an isosceles triangle AB=AC and BD and CE are its two medians. Show that BD=CE.

Bisectors of the angles B and C of an isosceles triangle with ABC with AB=AC intersect each other at O. show that the external angle adjacent to angleABC is equal to angleBOC .

AD is an altitude of an isosceles triangle ABC in which AB = AC. Show that:- AD bisects angle A .
