If the bisector of the exterior vertical angle of a triangle be parallel to the base. Show that the triangle is isosceles.

If the bisector of the exterior vertical angle of a triangle be parrallel to the base, show that the triangle is isosceles.

If the bisector of the vertical angle of a triangle bisects the base, prove that the triangle is isosceles.

If the bisector of the vertical angle of a triangle bisects the base of the triangle. then the triangle is isosceles. GIVEN : triangle A B C in which A D is the bisector of angle A meeting B C in D such that B D=DC TO PROVE : triangleA B C is an isosceles triangle.

If the bisector of the vertical angle of a triangle bisects the base of the triangle. then the triangle is isosceles. GIVEN : A A B C in which A D is the bisector of /_A meeting B C in D such that B D=D Cdot TO PROVE : A B C is an isosceles triangle.

If the bisector of the vertical angle of a triangle bisects the bese of the triangle;then the triangle is iscsceless.

If the bisector of an angle of a triangle bisects the opposite side, prove that the triangle is isosceles.

If the bisector of an angle of a triangle also bisects the opposite side, prove that the triangle is isosceles.

If the bisector of an angle of a triangle also bisects the opposite side, prove that the triangle is isosceles.

If the bisector of an angle of a triangle also bisects the opposite side, prove that the triangle is isosceles.

If the bisector of an angle of a triangle also bisects the opposite side, prove that the triangle is isosceles.
