Number of non-similar isosceles triangles ABC such that tan A+tan B+tan C=300 is equal to

Prove that the medians to the two equal sides of an isosceles triangle are equal.

In an acute-angled triangle ABC, tanA+tanB+tanC

In a triangle ABC tanA+tanB+tanC>=P then P=

If the areas of two similar triangles are equal, prove that they are congruent.

Prove that the ratio of the perimeters of two similar triangles is the same as the ratio of their corresponding sides.

Statement-1: In an acute angled triangle minimum value of tan alpha + tanbeta + tan gamma is 3sqrt(3) . And Statement-2: If a,b,c are three positive real numbers then (a+b+c)/3 ge sqrt(abc) into in a triangleABC , tanA+ tanB + tanC= tanA. tanB.tanC
