Lesson 6.2: Reflections

Lesson 6.2

Reflections

Some text here about the topic of discussion

​Definition

​Reflection: A reflection is a transformation where you flip your figure across an axis of symmetry. If your point is a certain distance from the axis of symmetry, your reflected point will be that same distance from the axis of symmetry.

​Reflection visual:

​What axis is the figure being reflected over?

Multiple Choice

Which one of these images show a reflection?

​How to preform a reflection:

​To preform a reflection, you need to count how many spaces your points are from the axis of symmetry.

​

​Lets Reflect the following points across the y axis:

​A (-2,2) B(-2,-2) C(-5,0)

Original images and reflected images are...

​Reflect the figure across the line y = 1. What will your new coordinate be?

Multiple Choice

Where should your reflected points be after a reflection across the y-axis?

• C(2,5) B(3,1) A(5,2)

• C(5,2) B(1,3) A(2,5)

• C(3,1) B(5,2) A(5,2)

• C(1,1) B(3,1) C(2,5)

Multiple Choice

Where will the point V be after a reflection across the y axis?

• (1,3)

• (1,-3)

• (-1,3)

• (1,-3)
