E-Math - Geometry - Angle Properties of Circle (2)

Topic:Geometry

When two tangents meet, they form an isosceles triangle (See diagram
above part a) Length TB = Length TA and Angle BAT = Angle ABT.
This property is called "tangents from an external point."
The other property that is useful is (See diagram part b) "angles in
alternate segment", though this property is used in A-Math, you are
allowed to use in E-Math and it help you find angles faster.
The quicker you solve the more time can be use to check.

About Unknown

I created this Blog after my students told me that there is very little information about how to solve GCE O Level Math and Additional Math (A-Math) questions on the internet. Even if they manage to find, the solution were for very basic questions. I am a Full-time Math Tutor in Singapore. I tutor mainly in Northern Singapore (Woodlands, Chua Chu Kang, Bukit Panjang, Yishun and Sembawang). I also tutor in Johor Bahru.
