back 咗ms lee d 野 :
Ch.1 Angles related with Lines and Rectilinear Figure
Different types of angles
1. If XY is a straight line, then
a+b=c=180degrees
the reason is adjacent angles on a straight line
2. If O is the common vertex, then
a+b+c=306degrees
The reason is angles at a point
3. If AB intersect PQ, then
X=Y
H=K
the reason is vertically opposite angles
