What you’ll learn

Three Ways to Move a ShapeName the three transformations: translation (slide), reflection (flip), and rotation (turn).There are three ways to move a shape without changing its size: a translation slides it, a reflection flips it over a mirror line, and a rotation turns it around a point. Each move keeps the shape exactly the same size and shape — only its position or direction changes.
Spotting TransformationsIdentify translations, reflections, and rotations in real examples and translate a shape on a grid.Transformations appear everywhere: a sliding door is a translation, a mirror image is a reflection, and clock hands going round show a rotation. To translate a shape on a grid, move every corner by the same rule and the shape keeps its size, just in a new spot.

Questions this course answers

A translation is when you…

A translation slides a shape without turning or flipping it.

Which transformation flips a shape over a mirror line?

A reflection flips a shape over a mirror line to make its mirror image.

Turning a shape around a fixed point is called a…

A rotation turns a shape around a point, like clock hands going round.

When you translate, reflect, or rotate a shape, its size…

All three transformations keep the shape the same size and shape — only its position or direction changes.

A sliding door moving straight sideways is an example of a…

The door slides in a straight line without turning or flipping, so it is a translation.

The hands of a clock going round show which transformation?

The hands turn around the clock's centre, which is a rotation.
