In an Isoceless triangle altitude from the vertex bisects the base.

In an isosceles triangle altitude from the vertex bisects the base.GIVEN: An isosceles triangle ABC such that AB=AC and an altitude AD from A on side BC. TO PROVE : D bisects BC i.e.BD=DC .Figure

In an isosceles triangle if the vertex angle is twice the sum of the base angles,calculate the angles of the triangle

In an isosceles triangle,if the vertex angle is twice the sum of the base angles,calculate the angles of the triangle.

Prove that of all the triangles with a given base and a given vertex angle, an isosceles triangle has the greatest bisector of the vertex angle.

The altitude from the vertex bisect the base in an isosceles triangle

If the altitude from one vertex of a triangle bisects the opposite side; then the triangle is isosceless.

If the altitude from one vertex of a triangle bisects the opposite side, then the triangle is isosceles. GIVEN : A A B C such that the altitude A D from A on the opposite side B C bisects B C i.e., B D=D Cdot TO PROVE : A B=A C i.e. the triangle A B C is isosceles.

In an Isosceles triangle the base angles are equal and the vertex angle is twice of each base angle. Find the measures of the angles of the triangle.

The altitude drawn to the base of an isosceles triangle is 8cm and the perimeter is 32cm. Find the area of the triangle.
