If in a triangle `PQR; sin P, sin Q, sin R` are in A.P; then (A)the altitudes are in AP (B)the altitudes are in HP (C)the altitudes are in GP (D)the medians are in AP

If in a triangle P Q R ,sinP ,sinQ ,sinR a r e i n AdotPdot , then (a)the altitudes are in A.P. (b)the altitudes are in H.P. (c)the medians are in G.P. (d)the medians are in A.P.

In the !ABC , the altitudes are in H.P., then

If in a !ABC , sin A, sin B and sin C are in A.P, then

In any triangle ABC, if sin A , sin B, sin C are in AP, then the maximum value of tan ""B/2 is

If the altitudes of a triangle are in A.P,then the sides of the triangle are in

If in a DeltaABC, sin A, sin B, sin C are in A.P., show that 3 tan, A/2 tan, C/2 = 1

If in a DeltaABC , the altitudes from the vertices A, B, C on opposite sides are in H.P, then sin A, sin B, sin C are in

In a /_\ABC, tan\ A/2 = 5/6 and tan\ C/2 = 2/5 then (A) a,c,b are in A.P. (B) a,b,c are in A.P. (C) b,a,c are in A.P. (D) a,b,c are in G.P.

Statement- 1: If the sines of the angles of a triangle are in A.P., then the altitudes ef the triangle are also in A.P. Statement-2: Twice the area of a triangle is equal to the product of the lengths of a side and the altitude on it.

If a,b,c are in AP and b,c,d be in HP, then
