In ∆ABC,D and E are the midpoints of AB and AC respectively.
Therefore,DE || BC (By converse of mid point theoram)
Also,DE =
In ∆ADE and ∆ABC
∠ADE = ∠B (corresponding angles)
∠DAE = ∠BAC (common)
∆ADE = ∆ABC (By AA similarity)
We know that the ratio of areas of two similar triangles is equal to the ratio of square of their corresponding sides.
☞ =
[AB = 2AB as D is the mid point]
☞ =
☞ =
Hence,the ratio of the areas ∆ADE and ∆ABC is area(∆ADE) : area(∆ABC) = 1:4
