Reflections (over x-axis, y-axis, y=x, and line x=-2)

What you’ll find in this video:
1) What are reflections? (0:18)
2) Reflection over x-axis(0:36)
3) Rigid Motion (2:14)
4) Reflection over y-axis (1:20)
5) Reflection over line y=x(2:37)
6) Summary of Reflections Basics (x-axis, y-axis, y=x) (3:40)
7) Reflection over line x=-2(3:57)
Reflections in a coordinate plane are exactly what they sound like! When a point, line segment, or shape is reflected over a line it creates a mirror image of itself. I always like to think of a butterfly or a page being folded in half, where there is perfect symmetry.
All reflections maintain something called Rigid Motion. This means that when a shape or line segments are reflected, the length and angles of all sides remain the same.

How do you do x=2? positive 2

[@MathSux]

You would draw a line where x=2 on the other side and reflect the same exact way. Check out the example below: www.desmos.com/calculator/4fbkcolykw

Thanks so much. My teacher made the variable parts next to the r extremely small so it was hard to pay attention to on the notes and I freaked out when I saw “in x=2 and y=-1”

[@MathSux]

Glad it helped!

I've been searching for a video on how to reflect over the x=2 line and this is as close as I got idk what to do-

[@MathSux]

It would be very similar to reflect over the line x=2. You would draw a vertical line where x=2 on the other side and reflect each point the same exact way. Check out the example here: www.desmos.com/calculator/4fbkcolykw Hope this helps!
