SIDES The three line segments `AB BC and CA` that form the triangle `ABC` are called the sides of the triangles `ABC.`

Sides the three line segments ABBC and CA that form the triangle ABC are called the sides of the triangle ABC.

Elements or parts the three sides AB BC CA and three angles A B C of a Delta ABC are together called the six parts of elements of the Delta ABC.

If D,E,F are the mid-point of sides AB,BC and CA respectively of triangle then the ratio of the areas of triangles triangleDEF and ABC is

D,E and F are the mid points of the sides BC, CA and AB respectivley of f triangle ABC then the ratio of the areas of triangle DEF and ABC =………..

If a triangle ABC, the incircle touches the sides BC, CA and AB respectively at D, E and F. If the radius of incircle is 4 units and if BD, CE and AF are consecutive integers, Find the lengths of sides of the triangle ABC.

D,E,F are the foot of the perpendiculars from vertices A,B,C to sides BC,CA,AB respectively,and H is the or the centre of acute angled triangle ABC, where a,b,c are the sides of triangle ABC, then
