[00:00:00]Most students confuse these two transformations. Here's the easiest way to understand reflection versus translation.

[00:00:07]Reflections and translations, two words that confuse most middle schoolers.

[00:00:12]Let's fix that. A reflection flips a shape across a line called the line of reflection. Think of a mirror. The shape doesn't change size or rotate. [music] It just flips to the other side. Every point stays the same distance from the line, just on the opposite side. A translation slides a shape from one place to another. No flipping, no rotating. Every point moves the same direction and distance. It's written as x + a, y + b. Quick trick, reflection equals mirror flip. Translation equals slide. Both keep the shape exactly the same size and shape. [music] Want hands-on math practice? Grow Wise School in Dublin helps grades 6 through 12 build real math skills. Visit the growwise.com. [music]
