一、概念辨析———三角形三条角平分线的性质与三边垂直平分线的性质的联系和区别区别:(1)名称不同:三角形角平分线的交点叫做三角形的内心;而三边垂直平分线的交点叫做三角形的外心.(2)性质不同:三角形角平分线的交点到三边的距离相等;而三边垂直平分线的交点到三个顶点的距
First, the concept of differentiation --- The triangular bisector bisector nature of the nature and the three sides of the vertical bisectoral nature of the connection and difference: (1) different names: the intersection of the triangular bisector is called the triangle’s heart; and the three sides of the vertical division The point of intersection of the line is called the triangle’s outer center. (2) The nature is different: the distance from the point of intersection of the triangle bisector to the three sides is equal; the distance from the point of intersection of the three perpendicular bisectors to the three vertices.
