How many circles you can draw from one centre?
Multitude
Does a square have a center or do only circles have centers?
A square does have a centre.
Do circles have the same center?
No not all circles have the same centre. If the circles formula is in the form x2+ y2=r2 then the centre is always the origin= (0,0). But if the formula for the circle is in the form (x-h)2+(y-k)2= r2 then the centre is the the opposite sign of the h and the k. Eg. (x+4)2+(y-9)2=16 the centre would be (-4,9) and the radius would be 4
What are concertic circles?
Concentric circles - are circles that share a common centre. A typical example - is dripping water into a bowl - where you'll see the ripples form and spread out to the edge of the container.
When are two circles concentric?
When they have the same centre. As a consequence, the distance between the two circles, along any common radial ray, is a constant.
What are Circles having same centre but different radii called?
Concentric circles are circles with the same common centre.
What is the meaning of concentric circles?
They are circles that have a common centre
What are Two circles with the same centre point called?
Concentric circles
Prove that if chords of congruent circles subtend equal angles at their centers then the chords are equal?
let the two circles with centre O and P are congruent circles, therefore their radius will be equal. given: AB and CD are the chords of the circles with centres O and P respectively. ∠AOB=∠CPD TPT: AB=CD proof: in the ΔAOB and ΔCPD AO=CP=r and OB=PD=r ∠AOB=∠CPD therefore by SAS congruency, ΔAOB and ΔCPD are congruent triangle. therefore AB=CD

If two circles have the same point then what are they called?
If you mean they both have the same centre - they're called 'concentric' circles.
What is the diffrerence between concentric and eccentric circles?
Concentric circles have the same centre point while eccentric circles although being within each other have differing centre points[the inner cirles are off centre].
Is concentric circle and congruent circle are they same?
No. Concentric circles have the same centre but not [usually] the same radius. Congruent circles have the same radius, but not [usually] the same centre. If you have two concentric congruent circles one will be exactly on top of the other.
What are coplanar circles that have a common center?
If they have a common centre, they are concentriccircles.
Does a square have a center or do only circles have centers?
A square does have a centre.
What does C do in netball and what do you do when you play it?
the C in netball is centre and the centre position starts with the ball before the whistle blows and they can go anywhere on the court,but the two semi-circles (shooting circles).
Do circles have the same center?
No not all circles have the same centre. If the circles formula is in the form x2+ y2=r2 then the centre is always the origin= (0,0). But if the formula for the circle is in the form (x-h)2+(y-k)2= r2 then the centre is the the opposite sign of the h and the k. Eg. (x+4)2+(y-9)2=16 the centre would be (-4,9) and the radius would be 4
