Turn your quadrilaterals notes into a concept map
DeckOwl reads PDFs, DOCX files, slides, text notes, or photos of a textbook page and builds a mind map you can edit and explore branch by branch. No credit card needed to start.
Why a quadrilateral concept map helps
Printable quadrilateral concept maps are common in geometry textbooks, but a ready-made sheet rarely matches the definitions and diagrams your teacher used. A map generated from your own material keeps your course's vocabulary and examples, so you study what will appear on the test.
- Put the general shape at the top and subtypes beneath it, such as parallelogram above rhombus and rectangle.
- Give angles, sides, and diagonals their own branches so you can compare properties across shapes.
- Write one defining property per node rather than a full paragraph, so the map stays readable.
- Revisit the map before a quiz and redraw it from memory to find the branches you have not learned yet.
Built from your material
Upload the worksheet, textbook chapter, or lecture slides your teacher used, so the map follows their definitions and examples.
Editable branches
Rename nodes, move shapes under the right parent, and add properties like equal sides or perpendicular diagonals as you learn them.
Explore the links
Collapse and expand each branch to see how parallelograms, trapezoids, and kites relate, then test yourself by redrawing from memory.
How it works
Upload your notes
Add a PDF, DOCX, PPTX, plain text, or a photo of the page. Text is read from images, so handwritten-to-printed pages work too.
Review the generated map
Check the main branches and sub-points against your class material, then edit anything that doesn't match your course.
Study from the map
Explore each branch, then turn key properties into flashcards or quiz questions to practice the shapes.
Quadrilaterals suit a concept map because the shapes nest inside each other. Every square is a rectangle and a rhombus, and every rectangle is a parallelogram. Seeing those links as connected branches makes it easier to remember which properties each subtype inherits.
Once the map exists, you can edit it as your understanding changes. Add missing properties, correct a branch that is in the wrong place, and keep one map per unit so review stays organized.

Frequently asked questions
How do I tell a rhombus from a parallelogram?
Every rhombus is a parallelogram, but a rhombus has four equal sides while a general parallelogram only needs opposite sides equal. Put the rhombus under parallelograms on your map and list its extra property as a child node.
What should the main branches of a quadrilateral concept map be?
Common main branches are parallelograms, trapezoids, and kites, with each subtype and its defining properties beneath it. Angles and diagonals often get their own branch so you can compare them across shapes.
Does DeckOwl export mind maps?
Exports are a paid feature: Plus includes PDF, DOCX, Anki, and CSV export, and Pro adds QTI 2.1 and Moodle XML. The free plan gives you 3 generations per month and lets you study in the browser.
Is a mind map enough to learn quadrilateral properties?
A map shows how shapes connect, but you still need to practice problems with side lengths and angle measures. Use the map to quiz yourself by covering branches and redrawing them from memory.
