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

D is a point on side BC ΔABC such that AD = AC (see figure). Show that AB > AD.

DeltaABC is an isosceles triangle in which AB = AC. Side BA is produced to D such that AD = AB (see figure). Show that /_BCD is a right angle.

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

In angleABC , D is a point on side BC, triangleABC such that AD. AC (see figure).

If in a triangle ABC, BC = 5, AC = 4, AB = 3. D, E are the points on BC such that BD = DE = EC, angle CAE = theta . Then

ABC is a triangle with angle B greater than angle C . D and E are points on BC such that AD is perpendicular to BC and AE is the bisector of angle A. Complete the relation angle DAE = 1/2 [(…..) - angle C]

In an isosceles triangle ABC, with AB=AC, the bisectors of /_B and /_C intersect each other at O. Join A to O. Show that: OB=OC

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

ABC is an isosceles triangle in which altitudes BD and CE are drawn to equal sides AC and AB respectively (see figure) Show that these altitudes are equal.
