Respuesta :

an isosceles triangle has always two twin sides, so if one side is 3 and another is 6, there's another twin that's either 3 or 6.

now, let's take a peek at a caveat, if the twin angle missing is say 3, then the triangle has sides 3, 3 and 6, but but but, if the two slanted sides are 3 each, and the base or bottom is 6, the only way the bottom can be 6 is if the other sides lie flat on top of it, in which case we no longer have a triangle, since it'll be just 3 pancaked flat-lines, so it can't be 3, it must be 6.

The length of the third side is 6.

What is the Isosceles triangle?

  • An isosceles triangle is a triangle that has two sides of equal length.
  • As the two sides of an isosceles triangle contain lengths 3 and 6, the length of the third side exists 6.
  • Note that as the triangle exists isosceles the third side would be equivalent to either of them i.e. 3 or 6.
  • But a sum of two sides in any triangle should be greater than the third, you cannot form a triangle if the third side exists 3.
  • Hence, the third side can just be 6.

Therefore, the correct answer is option B) 6.
