alos the diameter of a cirle is twice the radii right?
yes
So for this the answer is RS if it is asking me wut the diameter of A is?
yes
Also wut is the common tangents in this?
CD
]]>it is a true or false question??
The measure of angle CAD is (0.3)(arc GE minus arc CD)

]]>What is the measure of an angle formed by two secants intersecting inside the circle equals?
is it ½ the sum of the intercepted arcs?
]]>its asking me if:
RS is tangent to circle A at X.
I don't really understand this tangent stuff.....
]]>(ii) In equal circles (or in same circle), equal chords cut off equal arcs, and conversely; in equal circles (or in same circle), if two arcs are equal then their chords are equal.
arc AB = arc BC
]]>Is there a rule for this.. All of the problems on this page ask me if i can conlclude that they are equal, so is there a specific on how much info i need to conclude that they are equal?
Like this one, since it says the length of both I have the info i need right?
