In the given figure, ABC and DCB are right angled at A and D respectively and AC=DB. Prove that triangle ABC is congruent to traingle DCB.:



 

Hi,

Here is the solution:

Given: Triangles ABC and DCB are right angled at A and D, respectively. AC=DB
 
To prove: △ABC ≅△DCB
 
In △ABC and △DCB:
 
CAB=∠BDC  (90° each)  
 
BC=BC  (common)
 
ACDB  (given)
 
By R.H.S. congruence property:    △ABC ≅△DCB      


Important tip (as per the chapter): Learn and revise all the congruence rules. Solve and practice all the examples and question given in N.C.E.R.T Textbook (Maths). 

Cheers!!
