WebCircle theorems - Higher Circles have different angle properties described by different circle theorems. Circle theorems are used in geometric proofs and to calculate angles. WebPythagoras' Theorem. Let's start with a quick refresher of the famous Pythagoras' Theorem. Pythagoras' Theorem says that, in a right angled triangle: the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). a 2 + b 2 = c 2. That means we can draw squares on each side: And this will be true: A + B = C

WebCircle theorem includes the concept of tangents, sectors, angles, the chord of a circle and proofs. A circle is the locus of all points in a plane which are equidistant from a fixed point. The fixed point is called the centre of the circle, and the constant distance between any point on the circle and its centre is called the radius. WebCircle Theorems - Semicircle.
