Question

In triangle abc De is the line segment joining the midpoint of the side ab and ac if BC is equal to 8.5 cm find DE

Answer 1

Step-by-step explanation:

According to mid point theorem the line segment joining the mid-points of two sides of a triangle is parallel to the third side and equal to half the third side.

Here D and E are the mid points of side AB aand AC

⇒DE∣∣BC and BC=2DE

BC=4.6 cm

2DE=4.6 cm

DE=2.3 cm
