Students know the definition of reflection and perform reflections across a line using a transparency. Students show that reflections share some of the same fundamental properties with translations (e.g., lines
1 Αυγ 2024 · Whether you are just starting to explore reflections in math or need to brush up on your geometry, this simple, middle-school-friendly guide is for you. Read on to find easy-to-follow definitions and explanations, solved examples, and resources to help you learn and master reflections.
A reflection in math is a type of transformation that flips a shape across a line of reflection (also called a mirror line) so that each point is the same distance from the line of reflection as its reflected point.

A reflection is a flip over a line. You can try reflecting some shapes about different mirror lines here: "How Do I Do It Myself?" Just approach it step-by-step. For each corner of the shape: 1. Measure from the point to the mirror line (must hit the mirror line at a right angle) 2. Measure the same distance again on the other side and place a dot.
Reflection definition. In geometry, a reflection is a rigid transformation in which an object is mirrored across a line or plane. When an object is reflected across a line (or plane) of reflection, the size and shape of the object does not change, only its configuration; the objects are therefore congruent before and after the transformation.
REFLECTION Sometimes, a figure has reflectional symmetry. This means that it can be folded along a line of reflection within itself so that the two halves of the figure match exactly, point by point. Basically, if you can fold a shape in half and it matches up exactly, it has reflectional symmetry.
