Identify Line Reflection Worksheets

How to Identify Line Reflections - Geometric transformation is performed on different to make some changes in the form or size of shapes. These transformations are divided into four categories, translation, rotation, reflection, and dilation. Dilation involves changing the size of the shape without altering its form. Translation is thought to slide or move a shape to a new location. Rotation is defined as the type of transformation that includes spinning a shape around a fixed point. Reflection includes reflecting a specific shape across a fixed line of reflection. When we perform reflection on a shape, the initial figure is known as the pre-image, and the figure achieved after transformation is known as the image. The figures present before and after the reflection have the same shape and size. The figures are like the mirror image of each other present in opposite directions. The line of reflection is a line that lies between the two identical mirror images of 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 example, if you are given two triangles, each being a mirror image, you will use a ruler to measure the distance between the two points. Take the measured distance and divide it by 2 to calculate the exact halfway point and mark that point. Repeat these measurements and find out two more halfway points between two images. Use your ruler to connect all the three marked halfway points. If your measurements were correct, this will would be your line of reflection.

• Basic Lesson

Guides students through determining the presence of a reflection. Is this reflection? Remember a reflection in the Mirror. Does the left side become the right side and vice versa?

• Intermediate Lesson

Demonstrates how to use past concepts to determine if a reflection is present.
