A triangle with 2 equal side lengths is called an isosceles triangle.
Only if the triangle is degenerate.
An isosceles triangle has 2 equal sides and 1 side different in length
Right triangle (has one 90 degree angle). Isosceles triangle (has two equal length sides).
if two sides are of equal length, the a triangle is said to be isoceles.
An equilateral triangle is one where all sides are of equal length and all internal angles are 60 degrees. An isosceles triangle is one where 2 adjacent angles are of equal size and 2 adjacent sides are of equal length. A scalar triangle is one where no sides are equal in length and no angles are equal in size. A right-angled triangle is one where one of the internal angles is 90 degrees. The internal angles of all triangles always add up to 180 degrees.
Only if the triangle is degenerate.
A triangle that has two equal sides is called an Isosceles Triangle. It has two sides that are the same length and one side that is a different length. But for it to be a triangle, all the angles in the triangle have to add up to equal 180 degrees.
An isosceles triangle has 2 equal sides and 1 side different in length
Right triangle (has one 90 degree angle). Isosceles triangle (has two equal length sides).
An isoceles triangle is a triangle which has exactly two sides of equal length. The third side can be longer or shorter than the other two. The two sides being of equal length means that two of the angles are of equal size (not the one between the two equal-sized sides).Other types of triangleAn equilateral triangle is one where all three sides are of equal length and so all angles are of equal size. A right-angled triangle is one which has a right angle in it. It can be either an isoceles triangle or a scalene triangle. Scalene triangles are triangles where every side is of a different length and every angle is of a different size.
if two sides are of equal length, the a triangle is said to be isoceles.

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.

If an isosceles triangle is defined as one which has two sides (or angles) equal, then YES. But if an isosceles triangle is defined as one which has two sides (or angles) equal, and the third side (angle) different, then NO.
