# Identifying Line Reflection Worksheets

How to Identify Line Reflections - Reflection can be thought of as flipping or folding an object over the line of the reflection. In geometric reflection, the original object is known as the pre-image, and the reflected image is known as the image. The initial object and the reflected object have the same size and shape, but they are present in opposite directions. The objects look like the exact mirror images of each other with left and right reversed. The line of reflection is a line that lies between the two identical mirror images or reflected objects. The line is present in a way that any point on one image is of equal distance on the flipped or reflected image. For instance, if you are given two triangles, each being a mirror image, and you can plot the top angle of both the triangles. Use a ruler to measure the distance between the two points. Take the measured distance and divide it by 2 to figure out the exact halfway point and mark that point. Repeat these measurements and find out two more halfway points between two images. Using your ruler connect all the three marked halfway points. If you measured these points correctly, this will would be your line of reflection.

• ### Basic Lesson

Guides students through the determination of a image reflection. The reflection of an object is called its image. The line (where a mirror may be placed) is called the line of reflection. The distance from a point to the line of reflection is the same as the distance from the point's image to the line of reflection. A reflection can be thought of as a "flipping" an object over the line of reflection.

• ### Intermediate Lesson

Demonstrates how to find the presence of a reflection.

• ### Independent Practice 1

A really great activity for allowing students to reinforce the concepts. Example: A person is sitting 4 feet away from a mirrored wall. How far away from the person will his/her reflection appear to be?

• ### Independent Practice 2

Students draw and Identifying Line Reflection in assorted problems. The answers can be found below.
