Given:
DE is the line segment joining the mid-points of the sides AB and AC if BC = 7.2 cm
To find:
The length of the line DE
Solution:
In the given triangle DE is the line segment joining the mid-points of the sides AB and AC.
So,
As per the mid-point theorem of the triangle
DE is parallel to BC
DE is half of the length of the side BC
And it is given in the question that length of the side BC is 7.2
DE = 1/2 of BC
DE = 1/2 of 7.2
DE = 3.6 cm
The length of the line DE is 3.6 cm
