In this lesson I will teach you about congruent figures. The concept of congruence is extremely important in geometry and we will focus our attention on it in this chapter. When two figures have the exact same shape and size we describe them as being congruent. For example, exact copies of a toy car would be congruent because they have the same shape and size. There is a concept in geometry for figures that have the same shape but a different size- we call this concept similarity and we will be studying it as well. One of the most important concepts you will learn in the lesson is corresponding parts of congruent figures are congruent- much more about this in the video. Moreover this lesson will be the foundation of many important triangle theorems that you must master. Like always take excellent notes and practice is a must.
