Q: 5 In Fig. , ABC and BDE are two equilateral triangles such that D is the mid-point of BC. If AE intersects BC at F, show that
[Hint: Join EC and AD. Show that and , etc.]
Let join the CE and AD and draw . It is given that ABC and BDE is an equilateral triangle.
So, AB =BC = CA = and D i sthe midpoint of BC
(i) Area of ABC = and
Area of BDE =
