Question

. ln the fig 1, D and E are the mid points of the sides AB and AC respectively of the triangle ABC'lf BC = 5'6 cm' find DE'

Answer 1

Answer:

as we know that the line joining midpoint of a triangle is parallel to third side and half of it by midpoint theorem hence

BC= 2DE

so

5.6cm =2DE

5.6cm/2 = DE

2.8cm=DE

Hence the value of DE is 2.8 cm
