the perimeter of a certain isosceles right triangle is 16 + 16根号2,what is the length of the hypotenuse of the triangle?
选项是8,16,4根号2,8根号2,16根号2
我觉得是D啊,怎么想怎么不对
好像斜边我算成直角边了。知道了知道了

当然是16了,8平方加8平方不等于16根号2的平方,8根号2的平方加8根号2的平方等于16平方.

题目是说一个等腰锐角三角形的周长为16+16根号2。
我用排除法想的,若为8,4根号2,两边和小于第三边
若为16根号2两边之和已经大于周长了
若为8根号2,是个直角三角形
所以只有B,可以满足。就是底边很小啦
补充好像不对。。。。题目说的是直角三角形,直角三角形,斜边就是最长的那个。。。我还想复杂了。。。...

我之前做了个简易计算器的简单工厂模式,效果与你这个是一样的~~~~
你的抽象类Shape里面的方法area()和perimeter(),可以参考的计算器的GetResult()

具体的你看我的 简易计算器工程模式 代码:
C# 简单工厂之简易计算器
总共三个类:Operation.cs OperationFactory.cs Program.cs
Operation.cs 两个操作数,一个运算的虚方法GetResult(),该方法得出运算结果

1、如果用一个圆围成一个长方形,它的周长总共6cm,你能算出这个圆的面积吗?
[6/(2π)]^2 * π = 9/π (cm^2)
2、如果一个长方形周长40cm,长x cm,那它的宽是多少?
40/2 - x = 20-x (cm)
3、如果一个圆半径3cm,你能算出它的周长吗?
2*3*π = 6π (cm)
4、如果在一个边长4cm的正方形内画一个最大的圆,这个圆的周长是多少?
The diameter of the circle equals the length of the square,so its perimeter is 4π (cm).

一个三角形的周长是2005cm. 最长边比中等长边长330cm,中等长边比最短边长332cm. 它的边长分别是多少?
中=短+332 1
中=长-330 2
2005=长+中+短 3
1+2, 有:
2中=短+长+2
代入 3,有:
2005=2中+中-2
中=669
于是:
短=669-332=337
