Problem Solving (PS) | In the figure above, if triangles ABC, ACD, and ADE are isosceles righ

In general, isosceles right triangles have the following properties.

Notice that the hypotenuse = (√2)(length of oneleg)

So, let's label the sides of the BLUE triangle asfollows:



This means each leg of the RED triangle has length (√2)(x)



The hypotenuse of an isosceles right triangle = (√2)(length of one leg) . . .

. . . so the length of the hypotenuse = (√2)(√2)(x) =2x


This means each leg of the GREEN triangle has length 2x



What is the area ofΔADE?

Area of triangle =(base)(height)/2
