How do I figure this?

The question is can I conclude that arc AB = arc BC??

Re: How do I figure this?

Hi misheeru;

No, I don't think you can. Not without more information.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: How do I figure this?

You'd need more information. It looks like arc AB is bigger than arc BC, but to be sure you'd need annotations.

Re: How do I figure this?

ok thanks guys.

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?

Hi misheeru;

(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

Re: How do I figure this?

ok how about this?



its asking me if:

RS is tangent to circle A at X.


I don't really understand this tangent stuff.....

Re: How do I figure this?

Since the circle is inscribed in triangle and the circle touches all of the sides, aren't all the sides tangent to the circle?

Re: How do I figure this?

Yes, I believe you are right, they are all tangent sides to the circle.

Re: How do I figure this?

Also..

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?

Re: How do I figure this?

alos the diameter of a cirle is twice the radii right?

So for this the answer is RS if it is asking me wut the diameter of A is?

Also wut is the common tangents in this?

Re: How do I figure this?

I am stuck on this as well.


it is a  true or false question??

The measure of angle CAD is (0.3)(arc GE minus arc CD)
