GMAT 关于三角形的问题
Q31:
A certain right triangle has sides of length x,y,and z,where x < y < z.If the area of this triangular region is 1,which of the following indicates all of the possible values of y
answer :y > 2^(1/2)

直角三角形的三个边长度依次递增
z 显然是斜边
y 长的直角边
x 短的直角边
为了达到1的面积,y最小和x一样长,这个情况下,y^2 * 1/2 = 1
=> y = 1 也就是 2^(1/2)
