This bundle is the whole circle-theorems suite in one discounted download — the angle at the centre versus the circumference, the angle in a semicircle, angles in the same segment, the cyclic quadrilateral, and isosceles triangles made from two radii. Every card is a labeled circle diagram with one missing angle to find, covering the core circle theorems of high-school geometry. 179 unique cards per product. Every diagram is captured to scale from the Find-the-Angle interactive, and each card is
