In triangle `A B C` , base `B C` and area of triangle are fixed. The locus of the centroid of triangle `A B C` is a straight line that is a) parallel to side `B C` (b)right bisector of side BC (c)perpendicular to BC (d)inclined at an angle `sin^(-1)((sqrt())/(B C))` to side BC

If a, b,c are the lengths of the sides of triangle , then

In a triangle ABC,vertex angles A,B,C and side BC are given .The area of !ABC is

In triangle ABC, base BC is fixed. Then prove that the locus of vertex A such that tan B+tan C= Constant is parabola.

In a triangle ABC, right angled at C, find the value of tan A + tan B in terms of the sides a,b,c.

The sides of a triangle are in A.P. then the line joining the centroid to the incentre is parallel to (a)The largest side (b) The smaller side (C)The middle side (d)None of the sides

A variable triangle A B C is circumscribed about a fixed circle of unit radius. Side B C always touches the circle at D and has fixed direction. If B and C vary in such a way that (BD) (CD)=2, then locus of vertex A will be a straight line. parallel to side BC perpendicular to side BC making an angle (pi/6) with BC making an angle sin^(-1)(2/3) with B C

In a triangle ABC,if (cos A)/(a)=(cos B)/(b)=(cos C)/(c) and the side a=2 then area of triangle is and the side a=2

In a triangle ABC,(a+b+c)(b+c-a)=lambda bc if
