Also known as "triangular" Translated by Google No. 2 　　To not have three-point line, linking the two dual-line graphics. Points called "vertices", connecting two vertices of the segment called "edge" of each corner on both sides of the folder called "angles." Also known as the triangle. Translated by Google No. 3 　　There are three sides of the polygon. Triangle composed of the three segments called the triangle of edge; adjacent to the public on both sides of the triangle vertices as endpoints; from the vertices of the triangle were cited by the other two vertices of the ray angle formed, called the triangle's interior angle, called angle of the triangle . Angles of the adjacent supplementary angle is called the triangle exterior angle. Trilateral each other so called scalene triangle; have called on both sides of an isosceles triangle are equal; trilateral are equal is called equilateral triangle. Three angles of a triangle is called an acute angle acute triangle; there is a right angle corner is called a right triangle; one obtuse angle is called an obtuse triangle. Translated by Google No. 4 　　由不在同一直线上的三条线段首尾顺次连结所组成的封闭图形叫做三角形。 Triangle classification 三角形分类 　　acute triangle: three angles are less than 90 degrees. Translated by Google 三角形的性质 　　Heart: the intersection of the three angle bisectors, the triangle cut center of the circle. 　　Properties: to trilateral distance equal. Translated by Google 三角形的面积公式 　　(1)s△=1/2*ah（a是三角形的底，h是底所对应的高） 　　(2)s△=1/2*ac*sinb＝1/2*bc*sina＝1/2*ab*sinc（三个角为∠a∠b∠c，对边分别为a,b,c，参见三角函数） 　　(3)s△=√［s*（s-a）*（s-b）*（s-c）］ 【s=1/2(a+b+c)】 　　(4)s△=abc/（4r）【r是外接圆半径】 　　(5)s△=1/2*(a+b+c)*r 【r是内切圆半径】 生活中的三角形物品 　　雨伞、帽子、彩旗、灯罩、风帆、小亭子、雪山、楼顶、切成三角形的西瓜、火炬冰淇淋、热带鱼的边缘线、蝴蝶翅膀、火箭、竹笋、宝塔、金字塔、三角内裤、机器上用的三角铁、某些路标、长江三角洲等。 什么是三角形？ 　　Proof: do BC to extend the line to point D, through point C to AB, parallel lines to the point E 　　∵ ∠ BCD = 180 ° 　　Angles of a triangle is 180 degrees Translated by Google 解直角三角形： 　　a ^ 2 + b ^ 2 = c ^ 2, where a and b, respectively, for the two at right angles to the edge right triangle, c is the hypotenuse. Translated by Google 解斜三角形 　　c ^ 2 = a ^ 2 + b ^ 2-2ab * CosC Translated by Google 三角形的性质 　　13 the end equal to the triangle area ratio equal to its high ratio of high-equal to the triangle area ratio equal to the ratio of the end. Translated by Google 三角形为什么具有稳定性 　　∵ the third side of non-stretching or bending Translated by Google 三角形的边角之间的关系 　　(1) The three angles of a triangle is equal to 180 ° (in the sphere, the angles of a triangle is greater than 180 °); 　　(11) triangle of the median line parallel to the third side and equal to 1/2 of the third side. Translated by Google Special triangle 　　Similar triangles corresponding edge is proportional to the corresponding angles are equal Translated by Google 三角形的面积公式 　　................ | Ef 1 | Translated by Google Triangular items 　　Triangles congruent conditions Note: only three angles equal to not be able to launch two triangles congruent, nor can "the SSA" Translated by Google 三角形中的线段 　　Bisector of angle: point consisting of equidistant points to both sides of the straight line. Translated by Google 三角形相关定理 　　Of three Multiplied: AF / FB × BD / DC × CE / EA = AG, / the BD × BD / DC × the DC / AG = 1 Translated by Google 百科辞典 　　Segment (edge). Sometimes the triangle is defined as the plane by the sides of a triangle Translated by Google English Expression n.:  triangle,  trigon,  trilateral,  geometric figure withthree straight sides and three angles adj.:  equilateral,  scalene Related Phrases corner border math contain function geometry cyclopedia A senior high school math math axiom Meinielaosi axiom trigonometry triangle junior middle school math an equiangular triangle More results...
