Spatial Visualization: Rotation & Mirroring

Pairs of symbols may be rotated and/or mirrored. Determine if the top and bottom match after accounting for transformations.

Mental Model

• Normalize the top (0°), then rotate the bottom in 90° steps.
• Check mirrored vs. non-mirrored states.

Using the Positional Aid

Leverage the built-in positional aid: rotate clockwise/counterclockwise in 90° steps and flip horizontally/vertically with a single click. You can reset instantly. This delivers immediate visual feedback—no need to mentally simulate transformations—so you can focus on recognition speed.

Practice Plan

Start slowly to learn the effect of each operation; then reduce clicks to build speed.
