Mathematicians use the term isosceles in two slightly different ways.
The angles across from each equal side are also the same in an isosceles triangle. Un triángulo isósceles es un tipo de triángulo que tiene dos lados de igual longitud. The two angles of an isosceles triangle, opposite to equal sides, are equal in measure. In geometry, the word isosceles describes a triangle with two sides that are the exact same length. The Indo-European etymon is also conventionally compared with Latin scelus "misfortune resulting from the ill will of the gods, curse, wicked or accursed act, crime, villainy," a neuter s-stem that appears to match exactly Greek skélos, though if "crime" is secondarily developed from a sense "misfortune," with religious connotations, a connection with crookedness is less likely. An isosceles triangle is a type of triangle that has any two sides equal in length. The Perimeter of Obtuse Isosceles Triangle may be defined as the sum of the length of all three sides of the triangle. Borrowed from Late Latin isoscelēs, borrowed from Greek isoskelḗs "having equal legs, (of a triangle) having two equal sides, (of numbers) divisible into equal parts, even," from iso- iso- + -skelēs, adjective derivative of skélos (neuter s-stem) "leg," going back to an Indo-European base *skel- "bent," whence also Armenian šeł "slanting, crooked" with o-grade, Greek skoliós "bent, crooked, askew, devious" perhaps with a velar extension Germanic *skelga-/*skelha-, whence Old English sceolh "oblique, wry," Old Frisian skilich "squinting," Old High German skelah "crooked, oblique," Old Icelandic skjalgr "wry, oblique" A triangle that has two angles with the same measure also has two sides with the same length, and therefore it is an isosceles triangle. Webster's New World Similar definitions Advertisement Origin of Isosceles From Ancient Greek (isoskels), from (isos, equal) + (skelos, leg) another word of the same root is scalene.
