In an equilateral triangle ABC, AL, BM, and `CN` are medians. Forces along BC and BA represented by them will have a resultant represented by

In an equilateral triangle ABC, BD is a median. Prove that tan angleABD=cot angleBAD .

In an equilateral triangle ABC, the side BC is trisected at D. Then the correct relation is

Delta ABC is an equilateral triangle and D and E are midpoints of AB and BC respectively. Then the area of Delta ABC : the area of the trapezium ADEC is

Construct an equilateral Delta ABC in which BC = 5 cm.

An equilateral triangle ABC has its centroid at the origin and the base BC lies along the line x+y=1. Area of the equilateral Delta ABC is

If Delta ABC be an equilateral triangle and AD _|_BC , then AD^(2) =

In an equilateral triangle ABC, D is a point of BC such that 4BD = BC. Prove that 16AD^(2)=13BC^(2) .
