A vs Triangles in Geometry
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
A
Create unique geometric shapes through iterative affine transformations. Apply translations, rotations, and scaling to various objects with gradient coloring to generate visually interesting results.
- Affine transformation for shape creation
- Translation, rotation, and scaling
- Gradient coloring
- Supports circles, rectangles, stars, polygons, and lines
- Iterative shape generation

This app allows you to create interesting shapes using affine transformation. Affine transformation can do translation, rotation and scaling on object's coordinate. We do iterations, and in each iteration we apply the affine transformation on the object (circle, rectangle, star, polygon or line), coloured in gradient. At the end, you may like the result. Have fun.

"Triangles in Geometry" is an educational app that describes the triangle basics - (Acute, Obtuse, Right Angle) and then progresses to explain various centers in a triangle - (Centroid, Incenter, Orthocenter) and Area. The app also summarizes and explains with images, triangles Theorems, and Postulates ( Proofs). Review questions (Quiz) at the end of the section has a few problems based on the triangle Theorems and Postulates.
