[" 1.If "I" is the incentre of a triangle "ABC," then the ratio "IA:IB],[qquad IC" is equal to "]

If I is the incenter of a triangle ABC,then the ratio IA IB IC is equal to

If I is the incenter of a triangle ABC, then the ratio IA:IB:IC is equal to cosec (A)/(2):csc(B)/(2):csc(C)/(2)sin(A)/(2):sin(B)/(2):sin(C)/(2)sec(A)/(2):sec(B)/(2):sec(C)/(2) none of these

If I is the incenter of DeltaABC, then the ratio IA:IB:IC is equal to

If I is the incentre of a !ABC , then IA:IB:IC is equal to

If I is the incentre of a !ABC , then IA:IB:IC is equal to

The distance of the incentre of the triangle ABC from A is

In Delta ABC, angle A = 58^(@) . If I is the incentre of the triangle, then the measure angle BIC is :

In triangle ABC , angle A = 58^@ . If I is the incentre of the triangle, then the measure of angle BIC is:

If I is the incentre of triangle ABC and angle A = 60^@ , then the value of angle BIC is
