Which of the circles have their centers in the third quadrant?
(x + 9)2 + (y + 12)2 = 36 (x + 16)2 + (y + 3)2 = 17
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
What is the locus of the centers of circles that are tangent to a given circle O at a given point A on circle O?
Join the centre of the circle O and the point A .Extend it to both sides to form a line.This is the required locus
What are circles with the same radius?
Circles with the same radius are congruent circles.
What are Circles having same centre but different radii called?
Concentric circles are circles with the same common centre.
When are two coplanar circles concentric?
When the centers of both the circles are at the same point.

What are concentrict circles?
They're circles that may have different sizes but their centers are at the same point.
What is a tangent intersecting the segment joining the centers of the two circles?
They are the common tangents to the circles.
Define common internal tangent of 2 circles?
it intersects the segment joining the centers of two circles
Does a square have a center or do only circles have centers?
A square does have a centre.
How do you find an internal tangent of 2 circles?
you draw a triangle formed by the centers of the two circles and use pythagoean theorem
What is the value of the coordinate of every point on the xaxis?
It is called the ordinate.
Which of the following circles have their centers in the second quadrant?
clarify your question a bit man !
Circles circumscribed about a given triangle will all have centers equal to the incenter but can have different radii?
Yes, that is correct. Circles circumscribed about a given triangle will have centers that are equal to the incenter, which is the point where the angle bisectors of the triangle intersect. However, the radii of these circles can vary depending on the triangle's size and shape.
When your independent variable is plotted on the xaxis and the dependent variable is plotted on the yaxis?
.... then your graph is inverted.
Which of the following circles have their centers on the y-axis (x-0)squared (y 5) squared74?
Yes, it does.
