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:

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

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