[9.In/_ABC,AB=5cm,BC=8cm" and "CA=7cm." If "D" and "E" are mid points of "AB" and "BC],[" respectively,determine the length of DE."]

In Delta ABC, AB = 5cm , BC = 8 cm and CA = 7cm. If D and E are respectively the mid-points of AB and BC, determine the length of DE.

In Delta ABC, AB = 5cm , BC = 8 cm and CA = 7cm. If D and E are respectively the midd-points of AB and BC, determine the length of DE.

In Delta ABC, AB=12 cm, BC=16 cm and CA=20 cm If D is the mid point of AC then the length of BD is

In the adjoining figure, D and E are the mid-points of AB and AC respectively. If DE = 4 cm , then BC is equal to :

In Delta ABC,AB=6cm,BC=7cm and AC=5cm .The area of Delta ABC is

In the given DeltaABC , points D and E are mid points of AB and AC and also BC=6 cm then find DE.

In a triangle ABC, AB = 5 cm, BC = 6 cm and CA = 7 cm. If bisectors of angleA, angleB, angleC respectively meet sides BC, CA and AB at D. E, F and I be the incentre of the triangle then What is the length of AE ?

DeltaABC is an equilateral triangle. D, E and F are the midpoints of AB, BC and CA respectively. If AB = 8 cm, the perimeter of A DEF is ………. cm.
