In this video we discover what they all mean. The radius is the distance from the centre of a circle to a point on the circle. A diameter is the distance across a circle through its centre point. The circumference is the distance around the edge of a circle. A sector is the part of a circle enclosed by two radii of a circle and their intercepted arc. A pie-shaped part of a circle. A segment is the region between a chord of a circle and its associated arc. A tangent is a line that touches a circle at only one point. A chord is a line that links two points on a circle or curve (it doesn’t have to pass through the centre). An arc is a part of the circumference.

Let’s discover some more circle theorems so that we can solve all types of geometrical puzzles. We discovered these 4 theorems in part 1: Angle at the centre is double the angle at the circumference The angle in a semi-circle is 90 degrees Angles in the same segment are equal / Angles subtended by
