![]() ![]() The angle opposite the base is called the vertex angle, and the angles opposite the legs are called base angles. In the isosceles triangle given above, the two angles B and C, opposite to the equal sides AB and AC are equal to each other. Parts of an isosceles triangle For an isosceles triangle with only two congruent sides, the congruent sides are called legs. where a is the length of the congruent sides of the triangle and b is the length of the base of the triangle. Scalene triangle: These triangles have all sides of. The altitude of isosceles triangle h (a2 b2/4) You can also find the area of the isosceles triangle using the following formulas: A ½ (a2 b2 4) × b with all three sides. Area of an isosceles triangle is the region enclosed between three sides out of which two are equal. Equilateral triangle: As the name suggests, such triangles have all three lengths identical to each other. Find high-quality stock photos that you wont find anywhere. We can calculate the height using the following formula: h a 2 b 2 4. The area of isosceles triangle ½ × Base × Height The perimeter of isosceles triangle sum of its three sides written as, P 2a + b.

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. In an isosceles triangle, if two sides are equal, then the angles opposite to the two sides correspond to each other and are also always equal. The height of an isosceles triangle is calculated using the length of its base and the length of one of the congruent sides. ![]() 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" ![]()
