Circle Theorems - GCSE Maths - Steps, Examples

WebFirst circle theorem - angles at the centre and at the circumference. Second circle theorem - angle in a semicircle. Third circle theorem - angles in the same segment. Fourth circle theorem - angles in a cyclic quadlateral. Fifth circle theorem - length of tangents. Sixth circle theorem - angle between circle tangent and radius. WebThe tangent theorem states that a line is a tangent to a circle if and only if the line is perpendicular to the radius drawn to the point of tangency. Properties of a tangent One tangent can touch a circle at only one point of the circle. A tangent never crosses a circle, which means it cannot pass through the circle. WebNow for the theorems: 1. The angle at the centre is twice the angle at the circumference 2. The angle in a semicircle is a right angle 3. Angles in the same segment are equal 4. Opposite angles in a cyclic quadrilateral sum to 180° 5. The angle between the chord and the tangent is equal to the angle in the alternate segment optech-ma
