Question

If Triangle ABC ~ Triangle DBA and BC * DB = 16, find AB.​

Answer 1

Answer:

In triangle ΔABC and ΔDCB we have

AB=DC , AC=DB and BC=BC

then from SSS congruence ,ΔABC=ΔDCB

Answer 2

Answer:

4

Step-by-step explanation:

It is Given that BC.DB=16

Since the triangles ABC and DBA are similar,

AB/DB = BC/BA = AC/DA

So cross multiplying,

AB.BA = BC.DB

(AB)² = 16

AB = 4
