A scalene triangle is a triangle that has three unequal sides, such as those illustrated above. SEE ALSO: Acute Triangle, Equilateral Triangle, Isosceles Triangle, Obtuse Triangle, Triangle. CITE THIS AS: Weisstein, Eric W. "

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 the equilateral triangle as a special case.

In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, equilateral triangles are also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.

An obtuse triangle is one with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180°, no triangle can have more than one obtuse angle.]]> 2016-12-19 05:28:36 UTC https://padlet.com/19wintergi/gtltkfe23aee/wish/144258414 Right 19wintergi https://padlet.com/19wintergi/gtltkfe23aee/wish/144258438 an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.]]> 2016-12-19 05:29:38 UTC https://padlet.com/19wintergi/gtltkfe23aee/wish/144258438 Obtuse 19wintergi https://padlet.com/19wintergi/gtltkfe23aee/wish/144258453 obtuse angle definition. An angle that measures more than 90 degrees but less than 180 degrees. (Compare acute angle and right angle.) An obtuse triangle is a triangle in which one of the angles is an obtuse angle. (Obviously, only a single angle in a triangle can be obtuse or it wouldn't be a triangle.) A triangle must be either obtuse, acute, or right. ... with the angle opposite side .
