等腰或直角三角形都是特殊的三角形,等腰三角形特殊在边有腰与底之分,角有顶角与底角之分;直角三角形特殊在边有直角边与斜边之分,角有直角与锐角之分.因为这种特殊性,在求解有关特殊三角型的问题时往往需要按边分类或按角分类.但是有一个要素,不要忽视“它”的存在,即特殊三角形的顶点,特别在遇到三点组成的特殊三角形时,我们可以按其顶点进行分类.因为特殊三角形中
Isosceles or right triangles are all special triangles. Isosceles triangles have special points on the sides of the waist and the bottom. The corners have the top and bottom corners. The right triangles have the right side and the oblique side. The distinction between right angles and acute angles. Because of this particularity, it is often necessary to classify by edge or by angle when solving problems relating to a particular triangle. However, there is an element that does not ignore the existence of “it”, that is, special triangles. Vertices, especially in the case of special triangles with three points, we can classify them by their vertices because of the special triangles
