Classifying Triangles and Quadrilaterals
by Anonymous
Change angles and vertices to see how triangles and quadrilaterals are named by their properties, and how those names overlap.

About this app
An interactive elementary math app for classifying triangles and quadrilaterals by their properties. Move triangle angles and quadrilateral vertices or adjust shape controls to see how side lengths, angles, and parallel pairs determine names. A final name-finding activity checks whether learners can identify the most specific classification and understand that categories can overlap.
Use cases
- Elementary students learning shape classification
- Teachers demonstrating triangle and quadrilateral properties
- Parents practicing geometry concepts with children
- Learners reviewing angles, equal sides, and parallel sides
Features
- Interactive triangle activities for right, obtuse, isosceles, and equilateral triangles
- Quadrilateral activities for parallelograms, rectangles, rhombi, and squares
- Live displays of angles, side lengths, equal sides, and parallel pairs
- Four-question shape naming challenge with immediate feedback
- Reset and next-step controls plus optional sound toggle
