Examples, solutions, videos, worksheets, games and activities to help Geometry students learn about transformations on the coordinate plane. In this lesson, we will look at reflection. What is Reflection in Geometry?
Reflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the mirror line as its reflected point. E.g. Triangle P P has been reflected in the line x=4 x = 4 to give Triangle Q Q.
Here you will learn how to reflect 2D shapes on the coordinate plane and how to describe a reflection in math. Students will first learn about reflections in math as part of geometry in 8 th grade.

Examples, solutions, videos, and worksheets to help Grade 7 and Grade 8 students know the definition of reflection and perform reflections across a line using a transparency (tracing paper). Learn that a reflection maps lines to lines, rays to rays, segments to segments, and angles to angles.
Exercises to graph the images of figures across the line of reflection, reflection of points and shapes are here for practice. In addition, skills to write the coordinates of the reflected images and more are in these pdf worksheets, making them ideal for students of grade 5 through high school.
