In this article, we will provide the answer key for Lesson 2 2 reflections. Reflections are a key concept in mathematics and are often used to describe the transformation of a figure across a line or an axis. This lesson focuses on understanding and applying reflections to various figures.
First, let’s define what a reflection is. A reflection is a transformation that flips a figure across a line called the line of reflection. The line of reflection acts as a mirror, and the figure is reflected on the other side of the line, maintaining the same shape and size.
In Lesson 2 2, students are given different figures and asked to reflect them across a given line. They are required to identify the line of reflection and draw the reflected figure. The answer key will provide the correct line of reflection for each figure and show the correct reflection.
Understanding reflections is an essential skill in geometry and can be applied to real-life situations. For example, architects use reflections to design buildings with symmetrical features, and computer graphics use reflections to create realistic images. By mastering the concept of reflections, students will enhance their spatial reasoning and problem-solving skills.

Overview of Lesson 2.2 Reflections
In Lesson 2.2, we will be discussing reflections in geometry. Reflections are a type of transformation that involve flipping an object over a line of reflection. This line acts as a mirror, with the object being reflected on one side and its image appearing on the other side.
During this lesson, we will learn about the properties and characteristics of reflections. We will explore how to identify the line of reflection given an object and its image, as well as how to determine the image of an object after a reflection. We will also discuss the concept of congruence and how it relates to reflections.
- Understanding the line of reflection: We will learn how to identify the line of reflection by examining the positions of corresponding points on the object and its image.
- Determining the image after a reflection: We will explore the rule for reflecting a point across a line of reflection and apply it to find the image of an object.
- Applying reflections to real-world situations: We will discuss how reflections can be used to solve problems and analyze scenarios in various fields such as architecture, art, and science.
By the end of Lesson 2.2, you should have a strong understanding of reflections and be able to identify the line of reflection, determine the image of an object, and apply reflections to solve problems. This knowledge will be essential as we continue to explore transformations in geometry.

Tips for Checking Your Answers
When it comes to checking your answers, it’s important to approach it systematically in order to catch any errors you may have made. Here are some tips to help you with the process:
1. Double-check your calculations
One of the most common mistakes when solving math problems is making calculation errors. Take the time to go back over your work and ensure that you have added, subtracted, multiplied, and divided correctly.
2. Use estimation
If your answer seems way off or doesn’t make sense, try using estimation to verify if it falls within a reasonable range. Estimating can help you quickly identify errors in your calculations.
3. Re-read the question
Make sure you have fully understood the question and answered it correctly. Sometimes, misinterpreting the question can lead to incorrect answers. Take a moment to re-read the question and ensure that your answer aligns with what is being asked.
4. Check for consistency
If you have solved a problem using multiple methods or formulas, make sure that your answers are consistent. If they differ significantly, it’s a sign that you may have made an error during your calculations.
5. Compare with known values
If the problem provides you with known values or real-life examples, try comparing your answer to those. If they are vastly different, it’s worth revisiting your calculations to see if there was a mistake.
Remember, checking your answers is just as important as solving the problem itself. By following these tips, you can increase your accuracy and catch any errors before submitting your work.
