The Reflection Postulate

Almost a week ago, we have discussed about some properties of reflection. We have learned that the pre-image of a figure is congruent to its image. We have also observed that the pre-image and image mirror each other. We also say that the preimage and image are symmetric. In this post, we learn formally the […]

The Properties of Reflection

We take a break at our Basic Algebra Theorems proof as I introduce reflection. Although this is not about mathematical proof, we will use this concept in proving many theorems later. The Image and Pre-image We look at the mirror to see our reflection. Our reflection is our image. Unless the mirror is distorted, we […]
