imenicagramatika

In der Geometrie eine von drei sich schneidenden Gerade begrenzte Figur. Man unterscheidet ungleichseitige D. mit unterschiedl. Seiten und Winkeln, gleichseitige D. mit gleichen Seiten und Winkeln, gleichschenklige mit je zwei gleichen Seiten und Winkeln, rechtwinklige D. mit einem 90-Winkel, spitzwinklige mit einem Winkel über 90. Die Winkelsumme ebener D. beträgt 180, D. auf Kugeloberflächen bezeichnet man als sphärische D.

### 1.triangle

imenicamatematika

In geometry, a three-sided plane figure, the sum of whose interior angles is 180ş. Triangles can be classified by the relative lengths of their sides. A scalene triangle has three sides of unequal length; an isosceles triangle has at least two equal sides; an equilateral triangle has three equal sides (and three equal angles of 60ş). Triangles can also be classified by their angle measures: a right triangle has one right (90ş) angle; an acute triangle has three acute (less than 90ş) angles; an obtuse triangle has one obtuse (greater than 90ş) angle; an equiangular triangle has three equal angles. (All equilateral triangles are equiangular, and vice versa.) If the length of one side of a triangle is l and the perpendicular distance from that side to the opposite corner is h (the height or altitude of the triangle), its area A = ˝ (lh).
