The key difference is that while congruent shapes are the same size, similar shapes are different sizes. The origin of the word congruent is from the latin word congruere meaning correspond with or in harmony. These worksheets explains how to determine if shapes are similar and congruent or not, and students.

The Similarity Of Triangles, Like Their Congruency, Is An Important Concept Of Geometry.
