The
Symbolism. Various symbolic meanings have been associated with the vesica piscis: When arranged so that the lens is horizontal, with its two overlaid circles placed one above the other, it symbolizes the interface between the spiritual and physical worlds, represented by the two circles.
A Venn diagram uses circles that overlap or don't overlap to show the commonalities and differences among things or groups of things. Things that have commonalities are shown as overlapping circles while things that are distinct stand alone.
Summary: If two circles intersect at two points, their centers lie on the perpendicular bisector of the common chord.
Now, two circles of equal or unequal radii are said to be intersecting, if any one of the following two conditions are met: Either of the two circles meets at two distinct points and intersects the other circle at those points.
For intersecting lines, there is no symbol that is used.
When two circles touches one another at exactly one point, then we say that the two circles are tangent to one another. In this case, the two circles share a common tangent line at the tangent point.
If two circles touch each other externally or internally then the two centres and point of contact are collinear .
If two circles touch each other externally at some point and a direct common tangent is drawn to both circles, the angle subtended by the direct common tangent at the point where two circles touch each other is 90°.
Two Circles uses data to grow every revenue line in sports. And we do it for 150 of the world's leading sports properties.

Two circles are congruent if they have the same size. The size can be measured as the radius, diameter or circumference.
The circle is a universal symbol with extensive meaning. It represents the notions of totality, wholeness, original perfection, the Self, the infinite, eternity, timelessness, all cyclic movement, God ('God is a circle whose centre is everywhere and whose circumference is nowhere' (Hermes Trismegistus)).
The caduceus is also used as a symbol representing printing, again by extension of the attributes of Mercury (in this case associated with writing and eloquence).
Circles and ovals
These rounded shapes tend to send a positive emotional message of harmony and protection. The circle is often used in a logo to represent unity, commitment, love or community. Curves in general when used in shapes tend to be viewed as feminine in nature while straight lined shapes are more masculine.
Two circles will intersect at two points if the difference between their radius is smaller than the distance separating their centers. This can also be defined if the sum of their radius is greater than that of the distance separating their centers which is defined by 'd'.
Overlapping circles represent how ideas are similar (the inner circle) and different (the outer circles). It is used after reading a text(s) where two (or more) ideas are being compared and contrasted. This strategy helps students identify similarities and differences between ideas.
In geometry, tangent circles (also known as kissing circles) are circles in a common plane that intersect in a single point.
If the sum of the radii and the distance between the centres are equal, then the circles touch externally. If the difference between the radii and the distance between the centres are equal, then the circles touch internally.
Therefore, from two circles touching externally, three tangents can pass. So, the correct answer is three. Additional Information: Tangent is a straight line which touches the circle at a particular point.
The symbol for the intersection of sets is "∩''. For any two sets A and B, the intersection, A ∩ B (read as A intersection B) lists all the elements that are present in both sets (common elements of A and B). For example, if Set A = {1,2,3,4,5} and Set B = {3,4,6,8}, A ∩ B = {3,4}.
Parallel lines are lines that never intersect, and they form the same angle when they cross another line.
Two examples of intersecting lines are listed below: Crossroads: When two straight roads meet at a common point they form intersecting lines. Scissors: A pair of scissors has two arms and both the arms form intersecting lines.
Hence, two circles are also congruent if they have equal diameters.
