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

April 8, 2013 By Ai Ling Ong 2 Comments


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.

For those of you who have challenges with this topic, tell me what are the challenges you face in the comment section below.

Hi, I'm Ai Ling Ong. I enjoy coaching students who have challenges with understanding and scoring in 'O' Level A-Maths and E-Maths. I develop Math strategies, sometimes ridiculous ideas to help students in understanding abstract concepts the fast and memorable way. I write this blog to share with you the stuff I teach in my class, the common mistakes my students made, the 'way' to think, analyze... If you have found this blog post useful, please share it with your friends. I will really appreciate it! :)
