Lesson 4

Definition of Reflection and Basic Properties

Learner Outcome: I can define and perform reflections across a line and determine the properties of the images.

What is a reflection?

Watch the video below to begin learning about reflecting shapes. Make sure to answer the questions along the way.

Watch the following video showing you how to effectively use the simulation to reflect shapes over a line. Make sure to follow along and pause the video when necessary.

Directions: As you're working through the simulation, make sure to do reflections over the following lines:

x-axis

y-axis

x = -2

y = 1

You can also reflect your shapes over other lines of reflection as well. Throughout the simulation, you will have to answer the questions on the google form below. Read the questions before accessing the simulation so you know what to look for.
