in a figure DE||BC AD=3cm, BD =4cm and BC=14cm, then DE equals

In the given figure, AB||CD, AB=7cm, BD=25 cm and CD=17cm , find the length of side BC.

In the given figure, if DE || BC, AE = 8 cm, EC = 2 cm and BC = 6 cm, then find DE

In DeltaABC,D and E are points on the sides AB and AC respectively. Find whether DE||BC if (i) AD= 3cm , BD = 4.5cm, AE = 4cm, AC= 10cm (ii) AB=7 cm , BD = 4.5cm, AE = 3.5 cm, CE= 5.6cm.

In figure-2, DE||BC . If (AD)/(DB)=(3)/(2) and AE=2.7 cm then EC is equal to

In the figure chords AE and BC intersect each other at point D (i) If /_CDE=90^(@) AB=5cm BD=4cm and CD=9 cm find DE (ii) If AD=BD, show that AE=BC

In the DeltaABC ,DE||BC , AD=3, BD=6, and BC=8. What is the ratio of the areas of triangle ADE and trapezium BDEC?

In the given figure, BC = 8 cm and AD = 4 cm. AD || BC , find the area of DeltaEBC

In ∆DEW, AB || EW. If AD = 4 cm, DE = 12 cm and DW = 24 cm, then find the value of DB.

In the given figure, AB, BC and CA are tangents to the given circle. If AB= 12cm, BC= 8cm and AC= 10cm, find the length of AD, BE= CF

ABC is a right angled triangle with ABC = 90^@ . D is any point on AB and DE is perpendicular to AC. Prove that: If AC = 13 cm, BC = 5 cm and AE = 4 cm. Find DE and AD.
