The option (b) all congruent figures are also similar figures is true because congruent figures are similar in size and shape.
Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
Congruent figures are similar in size and shape. So they are comparable, yet they are not congruent because the figures may not be the same size.
Thus, the option (b) all congruent figures are also similar figures is true because congruent figures are similar in size and shape.
