等腰三角形两腰相等,这是我们常常注意和利用到的性质.由此性质不难推得等腰三角形腰长大于底边长的一半,而小于周长的的一半.本文举例说明利用这一关系解有关等腰三角形边长和周长问题.
The isosceles triangle has two equal waists. This is the property we often pay attention to and utilize. It is not difficult to push the isosceles triangle waist length to be greater than half the length of the base and less than half the circumference. This article illustrates the use of this A relation concerning the length and perimeter of isosceles triangles.
