Angle Exercise Builder

Generate ready-to-publish angle riddles in seconds. Pick a figure type and difficulty, and the builder draws a clean problem image, a solution image, and a three-step explanation you can paste straight into an article.

How to use it

Choose one of the four figure types — or leave it on Random — and a difficulty. Press Generate to draw a fresh puzzle, or Regenerate to reshuffle the numbers. Switch the puzzle language between Czech and English at any time. Download the problem and solution as SVG or PNG, or copy the whole article block.

The riddle format

Every puzzle uses one rule — angles on a straight line sum to 180°, the angles of a triangle sum to 180°, angles around a point sum to 360°, and the angles of a quadrilateral sum to 360°. The reader identifies the rule, adds the known angles, and subtracts to find the unknown angle α. The answer is always a whole number of degrees.
