Q2 of 18 Page 192

Draw two congruent figures. Are they similar? Explain.

We know that two figures are “congruent” if they have the same size, same shape and same angle.

When two figures are “similar”, their angles are same. But that does not mean they have to be congruent. Whereas “Congruent” figures are “always similar”.


Example 1:



Above two figures are congruent as they have same size, same shape and same angle and all congruent figures are similar.


Example 2:



Figures given above are similar as they have same angles but are not congruent.
