In a triangle ABC

In triangle ABC, if (cot A)/(2)=(b+c)/(a), then triangle ABC must be

There exist a triangle ABC satisfying

triangle ABC ~ triangle LBN .In triangle ABC ,AB=5.1 cm, /_B=40^@ ,BC=4.8 cm, AC/LN=4/7 .Construct triangle ABC and triangle LBN .

triangle ABC ~ triangle LMN .In triangle ABC ,AB=5.5 cm,BC=6 cm and CA=4.5 cm.Construct triangle ABC and triangle LMN such that BC/MN=5/4 .

The centroid of a triangle ABC is G. The area of triangle ABC is 60 cm^(2) . The area of triangle GBC is.

If in triangle ABC cosA/cosB =a/b then triangle ABC is

If I is the incentre of triangle ABC and angle BIC = 135^@ , then triangle ABC is यदि I त्रिभुज triangle ABC का अंतः केंद्र है और angle BIC = 135^@ तो triangle ABC है-
