Literally speaking, an isosceles triangle is one which has two sides of equal length. Generally speaking, the third side should be of a different length. [If the third side is also the same length then the triangle would be equilateral, but that may be considered a special case of an isosceles triangel.]
Equality of two sides implies that the two angles at the ends of the third side are of equal measure. This may be used as a working definition of an isosceles triangle.
