How to play

Each round presents a sequence of drawn figures, one per question. Read the diagram and answer by choosing from the options: classify an angle as acute, right, obtuse or straight, name a polygon by its sides, or work out a missing angle using facts like the angles in a triangle or on a straight line. Answer the round's set of questions, with your correct count and time tracked.

What you'll learn

Anglesmith builds angle and polygon fluency through quick, diagram-based questions, training you to read and reason about shapes at a glance.

Origins

Classifying an angle as acute, right, obtuse or straight from a drawn figure is geometry's first vocabulary.

Reading it off a diagram rather than from a stated measure is the original demand.

Diagrams are where the vocabulary is actually used and where it is least reliable. Figures are routinely not to scale, so a judgement has to come from the marked information rather than from how the drawing looks — which is the habit every later proof depends on.
