In `Delta ABC`, with `angle B=90^(@)`, BC=6 cm and AB=8 cm, D is a point on AC such that AD=2 cm and E is the midpoint of AB. Join D to E and extend it to meet at F. Find BF.

In figure, ABC is a triangle with angle B = 90^@, BC = 3cm and AB = 4cm. D is a point on AC such that AD = 1cm and E is the mid- point of AB. Join D and E and extend DE to meet CB extended at F. Then BF is equal to

In a Delta ABC, angle A=120^(@), AB =6 cm, AC=8 cm find the l,ength of side BC.

In a Delta ABC, AB=AC=17cm D is a point on BC such that AD=15, CD=4 cm , find BD=?

In Delta ABC , AB = AC and BC = 6cm, D is a point on the side AC such that AD = 5cm and CD = 4cm, show that Delta BCD ~ Delta ABC and hence find DB .

In a right triangle ABC, angle B = 90^@ : If AB = 6 cm, BC = 8 cm, find AC

In a triangle ABC, angle B=90^(@), AB=8 cm, BC=6cm . BD is perpendicular to AC, then find the length of CD, AD and BD.

(iv) In Delta ABC, angle ABC=90^@ and if AB=6 cm and BC= 8 cm , then find circum-radius of DeltaABC .
