Measure workshop

Mirror Line · think & focus

Copy across the dashed line.

A figure on a square grid, cut down the middle. Finish the other half, decide if a line is a true mirror, or spot the one that already matches — untimed.

No accounts · no timer · each square has a partner

Need it on paper? Symmetry drawing

Pick a way to practise

How would you like to look at symmetry today?

Choose one mode or take a three-part symmetry walk. Each round is untimed.

A gentle note: Mirror Line is for leisurely symmetry practice, not a measure of ability.
