Statements                  Reasons
Angle ABD is equals     Given
to Angle ACB. 
Angle BAD is equals      Same angle
to Angle BAC.

Thus, triangle ABD is similar to triangle ABC. (AA)

anonymous · Answer

Triangle ABD is similar to Triangle ABC because of what reason? @TURITW

anonymous · Answer

Did you learnt the conditions for similar triangles?

anonymous · Answer

Oooh, AA Theorem. Gotcha. Thank you!

anonymous · Answer

Actually angle ABC and angle ABD are different, it would be angle A= angle A by reflexive property
