About this app
Coordinate Plane Transformations is an interactive middle-school math app for exploring how triangles and points change on a coordinate plane. Adjust horizontal and vertical shifts, compare reflections, a 90° counterclockwise rotation, and dilations, then review the coordinate rules and whether the result is congruent or similar. A challenge section asks learners to identify image coordinates for individual points.
Use cases
- Middle-school students learning coordinate transformations
- Teachers demonstrating transformations on a coordinate grid
- Learners practicing reflection, rotation, translation, and dilation rules
- Students checking whether transformed figures are congruent or similar
Features
- Interactive triangle translation with adjustable x and y shifts
- Visual comparison of original and transformed figures on a coordinate plane
- Six selectable transformations: axis and origin reflections, 90° rotation, and two dilation scales
- Displayed coordinate rules and example point mappings
- Multiple-choice coordinate challenges with a correct-answer streak
