Similar figures are figures that have the same shape but are only different in size. Two triangles are similar even if one is bigger than the other. Congruent figures are the same size and the same shape. This would be two different triangles that you could stack on top of one another and there would be complete overlap with nothing sticking out. Basically, it is an exact copy of the same shape.

Congruent figures are one type of similar figure. Similar figures have the same shape. Their sides have the same proportions to one another. In that way, a square with sides of 2 cm is similar to a square with sides of 4 cm. Congruent figures, on the other hand, must be exactly alike A square with sides of 2 cm is only congruent to another square with sides of 2 cm.
