E-Maths: Introduction of Angle Properties of Circle (Basic) - Video

This topic, Angle Properties of Circle is usually introduced in Secondary 3 Elementary Maths syllabus in Singapore.  It is a very visual topic in which some students might have challenges "seeing" and "identifying" them.

I would like to first introduce the 5 Angle Properties of Circle:

  1. Angles in the same segment (are equal)
  2. Angle at centre is twice angle at the circumference
  3. Right angle in semi-circle
  4. Angles in opposite segment (add up to 180 degrees)
  5. Radius is perpendicular to tangent

I have shared these 5 Angle Properties of Circle in the following video.
