Geometry Question Generator

Draws a geometry recall question — a shape name, an angle rule, a formula — and holds its answer back behind a reveal, so it works as a starter you can run from the front without a textbook open beside you. Forty questions, each with a single short answer written alongside it rather than worked out afterwards.

Your geometry question will appear here.

What this generator does

Draws one of forty geometry recall questions and shows its answer only when you ask. The answer is drawn with the question rather than worked out, so this is a flashcard deck rather than a solver — which is why the questions ask for facts, names and formulas rather than for a diagram to be measured or marked.

What's in the question bank

This generator draws from 40 written questions, each stored with its answer. Every question is equally likely, and questions can repeat across separate draws — the tool does not track what it has already shown you.

What is the sum of the interior angles of a triangle?: 180 degrees
Each angle in an equilateral triangle is how many degrees?: 60 degrees
Each interior angle of a regular hexagon is how many degrees?: 120 degrees

A fixed sample so this page stays the same between visits. The answer is drawn with the question and held until you choose to reveal it, so pressing Reveal never changes what the answer is.

How to use this tool

Press New question.
Work it out, or let the class answer.
Reveal the answer to check, then press it again.

Common use cases

Geometry classroom practice
Maths warm-up questions
Homework revision

How this generator works

Each entry in the bank is a question and its answer written together, and the draw picks the pair. The forty are grouped by topic in the source — angles, triangles, quadrilaterals, polygons, circles, area and volume, solids and transformations — so the spread is a property of the bank rather than of the draw. There is no seed: each press is an independent secure draw, so the same question can come up twice in a row.

Limitations and good to know

Questions are facts, names and formulas to recall, not worked problems with numbers to substitute — for calculation practice the area, perimeter and angle worksheet generators are the better fit.
Forty questions will still come round again across a term of daily starters, and nothing records which ones a class has already had.
The answer is the one written in the bank, so questions with more than one acceptable phrasing are deliberately not in it. Nearly everything here has a single short answer; two — stating Pythagoras' theorem and saying what makes a polygon regular — need marking for sense rather than exact wording.
No diagrams. A question that only makes sense against a drawn figure cannot be asked this way, which rules out most of the angle-chasing a geometry lesson actually does.

Practical tips

Ask for the working rather than the answer; in geometry the method is almost always the thing being assessed.
Have squared paper to hand — a great many of these are much easier drawn than described.

Entries are chosen with your browser's cryptographic random number generator, so every entry on the list is equally likely. How Generate Random works.
