Step-by-step explanation:
We know that in a right angled triangle by Pythagoras theorem
a²+b²=c² ......................(i)
Also sides of the equilateral triangles will be a, b, c
Therefore areas of the equilateral triangle wil be √3a²/4,√3b²/4, √3c²/4
Now multiplying (i) by √3/4 we get
√3a²/4+√3b²/4=√3c²/4
This simply means that the sum of the areas of triangles on perpendicular sides is equal to the area of triangle on hypotenuse
