In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having two and only two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including theequilateral triangle as a special case.
By the isosceles triangle theorem, the two angles opposite the equal sides are themselves equal, while if the third side is different then the third angle is different.
By the Steiner–Lehmus theorem, every triangle with two angle bisectors of equal length is isosceles
