The medians CD and BE of an equilateral triangle ABC intersect each other at O. The ratio of Delta ODE:Delta ABC is equal to

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 .

Bisector of the angles B and C of an isosceles triangle ABC with Ab = AC intersect each other at O. Shown that external angle agjacent to angleABC is equal to angleBOC .

If the medians of two equilateral triangles are in the ratio 3:2, then what is the ratio of their sides?

ABC is a triangle median CD and BE intersects at point O then find the ratio of area (DeltaODE) : (DeltaABC) .
