What are two circles with the same radius?

Congruent Circles: Two or more circles with the same radius, but different centers.

Do two circles coincide when they have the same radius?

Two circles are congruent if they have the same size. The size can be measured as the radius, diameter or circumference. They can overlap.

How many tangents can 2 circles have?

three tangents
when considered two circles. There can be three tangents in common. The one tangent will be at the point of touching where the two circles are touching each other. The point of contact of both the circles.

Can two circles be tangent to the same line at the same point explain thoroughly?

A special property can be noted when the two circles are tangent to each other: As this common tangent line is perpendicular to both radii of each circle at that point, it follows that the two radii and the tangent point lie along the same line. Also, the two circles can be tangent in a different way.

What is a circle with radius 0?

In various high school textbooks, when the radius of a circle is zero, it is said that it is a degenerate circle of zero radius. That means we’re looking at a circumference of zero radius. Consequently, only one point belongs to the circumference, which is the centre.

When two or more circles have the same center point?

Two or more circles having same centre are called concentric circles.

What do you call circles with the same center?

Concentric circles are circles with a common center. The region between two concentric circles of different radii is called an annulus.

Are all radii of a circle equal?

By definition, all radii of a circle are congruent, since all the points on a circle are the same distance from the center, and the radii of a circle have one endpoint on the circle and one at the center. The length of the diameter is twice that of the radius. Therefore, all diameters of a circle are congruent, too.

When two circles touch externally the distance between the centre is?

Therefore, we can say that if two circles touch externally, then the distance between their centres is equal to the sum of their radii.

How do you find the center of a circle inscribed?

When a circle inscribes a triangle, the triangle is outside of the circle and the circle touches the sides of the triangle at one point on each side. The sides of the triangle are tangent to the circle. draw in the angle bisectors. The intersection of the angle bisectors is the center of the inscribed circle.

Can two circles be tangent to each other?

Two circles are tangent to each other if they have only one common point. Two circles that have two common points are said to intersect each other. Two circles can be externally tangent if the circles are situated outside one another and internally tangent if one of them is situated inside the other.
