# D and E are point

Here, by applying converse of Thale’s theorem we can conclude whether or not DE BC.

By Thale’s theorem,

Solving for ,

We need to find DB from given AB = 12 cm and AD = 7.2 cm.

DB = 12 – 7.2

DB = 4.8

…(i)

Solving for ,

We need to find EC from given AC = 10 cm and AE = 6.4 cm.

EC = AC – AE

EC = 10 – 6.4

EC = 3.6

…(ii)

As equation (i) is not equal to equation (ii),

it doesn’t satisfies Thale’s theorem.

Hence, we can say DE is not parallel to BC.
