A)The given statement is FALSE.
- Two congruent triangles are always similar.
- But two similar triangles not necessarily be congruent.
- This is because congruency is proved only when two shapes overlap each other completely.
- But similarity depends upon proportions.
- Even if the sides are not equal, but if they are equal in proportion then two triangles are said to be similar.
- This is not the case in the congruency of two triangles.
B)The given statement is TRUE.
- As mentioned above, two congruent figures are always similar.
- So even if with the same shape and size, two figures will be similar as well as congruent.
C)The given statement is TRUE.
- According to the property of similarity of triangles, two triangles are said to be similar if their corresponding sides are proportional.
- This is because the angles of the triangles remain equal but it is only the size that changes.
D)The given statement is TRUE.
- Two polygons are said to be similar if their corresponding sides are proportional.
- But provided that both the polygons have the same number of sides.
