If in ` A B C` , side `a , b , c` are in A.P. then `B > 60^0` (b) `B<60^0` `Blt=60^0` (d) `B=|A-C|`

If a,b,c are in A.P. then

If in Delta ABC , sides a, b, c are in A.P. then

If a, b, c are in A.P. then show that 2b = a + c.

If the angles A,B,C of Delta ABC are in A.P. And its sides a,b,c are in G.P., then a^(2), b^(2), c^(2) are in

If the angles A,B,C of a triangle are in A.P. and sides a,b,c, are in G.P., then prove that a^2, b^2,c^2 are in A.P.

If the angles A,B,C of /_\ABC are in A.P., and its sides a, b, c are in Gp., show that a^(2) , b^(2), c^(2) are in A.P.
