Question

In triangle ABC, D and E are the points on sides AB and AC respectively. Find whether DE is parallel to BC, if: (1) AB=9cm,AD=4cm,AE=6cm and EC=7.5cm. (2) AB=6.3cm ,EC=11cm, AD=0.8cm and AE=1.6cm​

Answer 1

Answer:

1)AB=6.3cm,AD=4CM,AE=6CM AND AC=7.5CM

Answer 2

Answer:

they are parallell

Step-by-step explanation:

i ae=6

ec=7.5

therefore AE/EC=4/5

AB=9 AND AD=4 SO BD =5

SO AB/BD=45

THERE RATIOS ARE EQUAL AND IT CAN HAPPEN ONLY IN BPT BPT IS POSSIBLE ONLY WHEN LINES ARE PARALLEL
