Let there are two triangle ABC and ABD such that `AB = 17, AC = AD = 13, BC < BD and /_ ABC = /_ABD = sin^-1 (5/17)`, then

In two triangle ABC and DEF, AB= DE ,BC=DF and AC =Ef then

In Figure,ABC and DBC are two triangles on the same base BC such that AB=AC and DB=DC .Prove that /_ABD=/_ACD

For a triangle ABC ,D and E are two points on AB and AC such that AD=(1)/(4)AB,AE=(1)/(4)AC . If BC = 12 cm, then DE is

In figure , D and E are Points on side BC of a Delta ABC such that BD = CE and AD = AE . Show that Delta ABD cong Delta ACE.

In Figure,ABC and DBC are two isosceles triangles on the same base BC such that AB=AC and DB=CD. Prove that /_ABD=/_ACD

Delta ABC is a right triangle right angled at A such that AB=AC and bisector of /_C intersects the side AB at D.Prove that AC+AD=BC .

D is a point on side BC of triangle ABC such that AD = AC (see figure). Show that AB gt AD .

Let ABC be a triangle and D and E be two points on sides AB such that AD = BE . If DP || BC and EQ || AC , then prove that PQ || AB .
