What is meant by touching circle?
Answer: Two circles are said to touch each other if they have only one point common – a common tangent can then be drawn to both the circles at that point.
When two circles touch internally the distance between the Centre is?
If two given circles are touching each other internally, use this example to understand the concept of internally toucheing circles. This shows that the distance between the centers of the given circles is equal to the difference of their radii.
Can concentric circles touch?
Concentric Circles : Two circles may touch each other either internally or externally. Let C1, C2 be the centers of the circle and r1, r2 be their radii and P the point of contact.
What is the intersection of two circles called?
The intersections of two circles determine a line known as the radical line. If three circles mutually intersect in a single point, their point of intersection is the intersection of their pairwise radical lines, known as the radical center.
What are orthogonal circles?
Orthogonal circles are orthogonal curves, i.e., they cut one another at right angles. By the Pythagorean theorem, two circles of radii and whose centers are a distance apart are orthogonal if. (1) Two circles with Cartesian equations.
What are congruent circles?
Circles having the same radii are said to be congruent of one another. Circles having the same radii are said to be congruent of one another. When two circles are congruent, we can also say that they have the same area and circumference. Thus they can also be said to be equal circles.
What is the difference between two circles that are tangent and two circles that are concentric?
Tangent: A line that intersects a circle in exactly one point. Concentric Circles: Two or more circles that have the same center, but different radii. Congruent Circles: Two or more circles with the same radius, but different centers.
How many points are common when two circles touch each other?
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.
What does CDE describe?
A cardholder data environment (CDE) is a computer system or networked group of IT systems that processes, stores and/or transmits cardholder data or sensitive payment authentication data.
What are Nonconcentric circles?
1. nonconcentric – not having a common center; not concentric; “eccentric circles” eccentric. Based on WordNet 3.0, Farlex clipart collection.
What is a circle pattern called?
7. 19. An overlapping circles grid is a geometric pattern of repeating, overlapping circles of an equal radius in two-dimensional space. Commonly, designs are based on circles centered on triangles (with the simple, two circle form named vesica piscis) or on the square lattice pattern of points.
What is coaxial circle?
Coaxal circles are circles whose centers are collinear and that share a common radical line. Note that not all circles sharing the same radical line need be coaxal, since the lines of their centers need only be perpendicular to the radical line and therefore may not coincide.
