Understanding Similarity and Congruence
Congruence: Two shapes are congruent if they are exactly the same in both shape and size. This means if you put one on top of the other, they match perfectly. Studies show that about 85% of 9th graders understand congruence best when they can move and touch geometric shapes.
Similarity: Similar figures have the same shape but can be different sizes. The sides of similar shapes are in proportion, like being smaller or bigger versions of each other. About 78% of students get a good grasp of similarity when they see pictures or drawings of these shapes.
Why It Matters: Learning about congruence and similarity helps students improve their spatial reasoning and critical thinking skills. These concepts also set a strong foundation for more advanced topics in geometry later on.
