Question

In triangle abc ab=5cm bc=8cm CA=7 cm d and e are respectely the mid points ab and bc find de

Answer 1

de is the half of ac by mid point theorm so de=1/2bc so de=4

Answer 2

Answer:

In ΔABC, we have AB = 5cm, BC = 8 cm and CA = 7 cm. Since, D and E are the mid-points of AB and BC, respectively.

By mid-point theorem, DE || AC

and

DE = 1/2 AC = 7/2 = 3.5 cm
