Anglesmith
Step up to the forge where every blueprint is a geometry question — classify the angle, name the shape, or solve the missing degree to complete it.
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.
- Classify angles by type from the drawn figure.
- Name polygons by their number of sides.
- Solve for missing degrees using angle-sum and straight-line rules.
- Each round is a fixed set of figures to work through.
Game modes
- Daily: the same round for everyone, in Easy, Medium, or Hard.
- Practice: reshuffled rounds at your chosen difficulty.
Controls
- Desktop: click an answer option for each question.
- Phone & tablet: tap an answer choice to lock it in.
Tips & strategy
- Anchor your angle classification on the right angle — compare each angle to 90 degrees first.
- Recall the key sums: a triangle's angles total 180 degrees, angles on a line also 180.
- Count a polygon's sides carefully before naming it; one missed side changes the answer.
