in  the ncert solutions why isn't there the 8 th  question but 7,9,10 like that? in my text there is an 8 th question . please answer me.

the 8th question is

draw a rough sketch of two triangles such that they have five pairs of congruent parts but still the triangles are not congruent.

please give the answer to this question. 

Dear Student

When you have any two triangles such that they have five pairs of congruent parts, you can conclude that these two triangles are congruent by using any of the criteria (except RHS criterion, if triangles are not right angled).

Thus, such triangles can not be drawn.

 

Cheers!!
