Delta ABC is an isosceles triangle and AB = AC. If all the sides AB. BC and CA of a Delta ABC touch a circle at D, E and F respectively. Then BE is equal to :

If the middle points of the sides BC,CA and AB of triangle ABC are (1,3),(5,7) and (-5,7), respectively,then find the equation of the side AB.

If a straight line intersects the sides AB and AC of a triangle ABC at D and E respectively and is parallel to BC , then (AE)/(AC) = . ………..

If AB, BC, CA are three sides of triangle ABC having length 10,7,8 respectively then the projection of sides AB on BC is
