ABC is an isosceles right angled triangle with ∠B = 90°. On the sides AC and AB, two equilateral triangles ACD and ABE have been constructed. The ratio of area of ∆ABE and ∆ACD is
-
- 1 : 3
- 2 : 3
- 1 : 2
- 1 : √2
- 1 : 3
Correct Option: C
Using Rule 6,
AB = x units
BC = x units
AC = 2 x units [Using Pythagorus]
