Question

in triangle ABC if D and E are midpointd of AB and AC show that DE is parallel to BC​

Answer 1

Answer:

as d e are the mid ponts so the ratio of both sides are equal

by converse of thales theorem they are parallel

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

D and E are the midpoints of AB and AC respectively

Therefore

AD=BD

AD/BD=1

similarly

AE=EC

AE/EC=1

therefore AD/BD=AE/EC

By coverse of Basic proportionality theorem DE parallel to BC
