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.

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

This was great,it was helpful for me to clear my basic concepts.

Thank you. :)
