If ΔFGH is isosceles and FG < 3 cm, GH = 8 cm, then of the following, the true relation is.
Given : GH = 8cm and FG < 3 cm
Also, $$\triangle$$FGH is isosceles.
Solution : Since, FG < 3, => It can only be either 1 or 2.
case 1 : If FG = 1 cm
$$\because$$ Sum of any two sides of a triangle is always greater than the third side.
Since it is an isosceles triangle, if FG = FH = 1
The, above property will be contradicted as then, FH + FG will not be greater than HG(8).
=> Hence, the two equal sides are GH and FH
case 2 : If FG = 2 cm
As mentioned above, here also the two possible equal sides are GH and FH
=> GH = FH
