edexcel_igcse_mathematics a_topic 30_circle properties_015_

4.6.1 Recognise the terms ‘centre’, ‘radius’, ‘chord’, ‘diameter’, ‘circumference’, ‘tangent’, ‘arc’, ‘sector’ and ‘segment’ of a circle

A chord is a line segment joining two points on the circumference of a circle.

A line segment drawn from the centre of a circle to the midpoint of a chord will intersect the chord at right angles.

A tangent is a straight line that touches a circle only once.

A tangent and radius meet at right angle.

4.6.2 Understand chord and tangent properties of circles
