What does similar mean in mathematics?
Two shapes are said to be similar if they have the same angles, and the crresponding sides are all in the same proportion.
What does congruent mean if shapes are not the same size?
You can have two shapes - a small one and a big one - whose angles are congruent but the sides are not. In that case the shapes are not congruent but similar.
Can two shapes that are similar be congruent?
no
Can two shapes be congruent and not similar?
In short, no. Similar shapes are shapes in which all corresponding angles congruent regardless of the length of the sides. Congruent shapes have congruent corresponding angles and corresponding sides. In effect congruent shapes is a special condition of similar shapes.
