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

BE and CF are two equal altitudes of a triangle ABC. Using RHS congruence rule, prove that the triangle ABC is isosceles.

The exterior angle of a triangle must be___of its two opposite inferior angles.

If the bisector angle A of the triangle ABC makes an angle theta with BC, then sin theta=

If one side of a triangle is double the other, and the angles on opposite sides differ by 60^(@) then the triangle is

Two triangles are congruent, if two. Angles and the included side of one triangle are equal to two angles and the included side of the other triangle.
