Can the concentric circles intersect each other at any point?
Concentric circles are circles with a common center. The region between two concentric circles of different radii is called an annulus. Therefore, the two concentric circles have zero intersecting points; it means the option (D) is correct. So, the correct answer is “Option D”.
Do concentric circles intersect at two points?
Concentric Circles do not Intersect.
Do concentric circles have different radii?
The circles with a common centre are known as concentric circles and have different radii. In other words, it is defined as two or more circles that have the same centre point. The region between two concentric circles are of different radii is known as an annulus.
What is the space between two concentric circles called?
Concentric circles are circles with a common center. The region between two concentric circles of different radii is called an annulus.
How many common points do two concentric circles have?
Answer: there are two common points.
Where does the Centre of the circle lies?
interior
Centre is the reference point through which we can form a circle, So it will lie in the interior of the circle. Thus, The Centre of the circle lies in the interior of the circle.
Can two circles be both concentric and congruent?
Two circles that have the same center point are called concentric circles. We will now show that a secant line that intersects both of the concentric circles creates two congruent segments between the two circles.
What are circles having same centre and different radii called?
Circles with the same centre and different radii are called concentric circles.
What do you call circles which have the same center but unequal radii?
The circles having same centre but different radii are called as concentric circle.
What are concentric circles on a hard drive called?
A group of concentric circles (tracks) define a single surface of a disks platter. Early hard disks had just a single one-sided platter, while today’s hard disks are comprised of several platters with tracks on both sides, all of which comprise the entire hard disk capacity.
Are concentric circles similar?
All circles are similar! Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another. The circles are now concentric (they have the same center).
How many radii of a circle have the same length?
By the definition of a circle, any two radii have the same length. Notice that the word ‘radius’ is being used to refer both to these intervals and to the common length of these intervals. An interval joining two points on the circle is called a chord.
Are two circles with the same radius always congruent?
Any two circles with the same radius are congruent− if one circle is moved so that its centre coincides with the centre of the other circle, then it follows from the definition that the two circles will coincide.
What is the difference between lines and circles?
Lines and circles are the most elementary figures of geometry − a line is the locus of a point moving in a constant direction, and a circle is the locus of a point moving at a constant distance from some fixed point − and all our constructions are done by drawing lines with a straight edge and circles with compasses.
Are the theorems of circle geometry intuitively obvious?
The theorems of circle geometry are not intuitively obvious to the student, in fact most people are quite surprised by the results when they first see them. They clearly need to be proven carefully, and the cleverness of the methods of proof developed in earlier modules is clearly displayed in this module.
