Question

In the given figure, angle B = angle D =90degree and AB = DE . Prove that CD =BC​

Answer 1

Step-by-step explanation:

in triangle ABC and DEC

WE HAVE ,

angle B = angle D = 90° each

AB = DE ( Given )

•°• angle ACB = DCE ( vertical opposite angle )

•°• Triangles are congruent

•°•BC= CD (by CPCT)

Answer 2

Step-by-step explanation:

in triangle ABC and DEC

WE HAVE ,

angle B = angle D = 90° each

AB = DE ( Given )

•°• angle ACB = DCE ( vertical opposite angle )

Triangles are congruent (by SAS criterion )

•°•BC= CD (by CPCT)...
