An isosceles triangle has 3 sides 2 of which are equal in length
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.
The length of the third side of this triangle must be greater than 1 foot and less than 5 feet, and the third side would be either 2 feet or 3 feet if it were an isosceles triangle.
An equilateral triangle, by definition, has three sides of equal length. The definition for an isosceles triangle is that it must have two sides of equal length, the other side being free to have any length. Based on these two definitions, we can say that an equilateral triangle is a special case of the isosceles triangle, namely one where the third side is also equal to the other two sides.

An isosceles triangle has 3 sides 2 of which are equal in length
If two sides of a triangle each have length of 45 units, then the triangle is isosceles,and the third side can have any length less than 90 units.
An isosceles triangle. It is an isosceles triangle even if the third side is shorter.
Perimeter of the isosceles triangle: 16.2+16.2+8.1 = 40.5 cm
The congruent sides of an isosceles triangle are the two sides that are equal in length. These two sides are opposite the equal angles of the triangle. The third side, called the base, is not equal in length to the other two sides.
The third side would be either 5 or 8,as an isosceles triangle has 2 equal sides.
Using the cosine rule: 13.0112367 cm The triangle is in fact an isosceles triangle.
