This lesson explains key terms such as centre, radius, diameter, chord, and tangent using clear language and everyday examples. By the end of the video, learners will be able to: - Understand what a circle is - Identify the fixed central point (centre) of a circle - Recognize and define the radius, diameter, chord, and tangent - Use correct mathematical vocabulary with confidence Khan Academy video https://cdn.kastatic.org/googleusercontent/ZCdwTudJg6e6n-P2gsaUborP4izvMsGo71pvEVlX9dNYWcLXcP7VHkWpn2grt4TUP1KoJLQP9NswyHBuBLSFTBw Understanding the Circle In this video, students will learn about the circle and its important parts in a simple and engaging way.
