Classifying Polygons

Start with polygon names

The polygon names flashcards provide a starting point for becoming familiar with shapes in this collection. They include pentagons, hexagons and octagons, along with triangles and quadrilaterals such as squares, rectangles, rhombuses and kites. Work through the names, then return to any that you want to practice again.

For vocabulary beyond shape names, the Geometry Flashcards cover terms including side, vertex and diagonal. They also include regular, irregular, concave and convex polygons, as well as interior and exterior angles.

Explore the classifications

After the flashcards, use the Classification of polygons mind map to see how the topic is organized. It groups polygons by angles, sides and number of sides, and includes regular, irregular, convex and concave categories. Look for the names you met in the flashcards as you move through the map.

The Polygons mind maps offer more ways to explore the topic. They include triangles grouped by sides or angles and quadrilaterals such as squares, rectangles, rhombuses and parallelograms. Different maps include different selections of shapes, so comparing them can help you focus on the terms you want to practice.

Use maps and flashcards together

Move between a map and the flashcards rather than treating each resource as a separate task. For example, find a shape on a map, recall its name, then check it in the polygon names deck. Use the vocabulary deck alongside the classification map when working with terms such as convex and irregular.

There are no quizzes on this topic page, so the flashcards provide a way to practice recall while the maps show connections between terms.

Place the topic in its unit

Classifying Polygons is a section of the Quadrilaterals and Polygons unit in Mathematics. The resources on this page bring the shape names and classification terms together within that unit. Pick a map and a flashcard deck to explore them side by side.
