1. In ∆ABC and ∆BAD,
AB = AB (common)
AC = BD (Given)
BC = AD (Given)
So, ∆ABC = ∆BAD by SSS congruency.
2. Yes, angle A = angle B by CPCT

Step-by-step explanation:
[tex] \frac{ad}{db} = \frac{ae}{ec} [/tex]
we are given a triangle ABC in which a line parallel to side BC intersect other two sides ab and AC and DC and ac respectively we need to prove that.
letters join B and CD and then draw a perpendicular AC and EN perpendicular AB .
now area of triangle ADE equal to one half base into height equal to one half AD into EN
AREA ∆ ADE
[tex] = \frac{1}{2} ad \times en[/tex]
AREA ∆
