(0:01)What is a Circle? : A circle is defined by all points equidistant from its centre. This constant distance from the centre to any point on the circle is called the radius.
(0:30)Key Properties of Circles: The diameter is twice the radius. A chord is any line segment connecting two points on the circle, with the diameter being the longest chord.
(0:50)Segment and Sector of a Circle: A segment is the area between a chord and its arc, while a sector is the “pie-slice” area formed by two radii and the arc between them.
(1:11)Tangent of a Circle: A tangent is a line that touches the circle at a single point and is always perpendicular to the radius at that point of contact.
