What defines a chord in geometry?
A chord is a straight line that extends from one point of the circumference of a circle to another point on the circumference and the diameter of a circle is its largest chord
What is pi radius and diameter?
The radius of a circle is the distance from the center to any point on the circle. The diameter is twice as much; it is the length of a line segment from one point on a circle to another point on it that passes through the center. Pi is a constant, equal to approximately 3.1416 (the exact value is irrational), which is defined as the ratio of the circumference of any circle to its diameter (all circles are similar so the ratio is always the same).
Why are circles important to building equilateral triangles?
The three vertices of a circle are at the same distance form each other. The circumference of a circle identifies all points which are at a given distance from a point (vertex).
Why are radius and diameter different?
The radius is half of the diameter. The radius of a circle is the distance from the centre to the circumference. The diameter of a circle is the length of a straight line from one point on the circumference to another, passing through the centre of the circle.
What is the relationship between radius diameter and circumferences of circles?
Radius is the distance from the center point to the edge of the circle. Diameter is the distance straight through the center point and across the circle. Circumference is the distance one full turn around the circle. Radius = 1/2 of the diameter Radius = (circumference) divided by (2 pi) Diameter = 2 times the radius Diameter = (circumference) divided by (pi) Circumference = (pi) times the diameter Circumference = (2 pi) times the radius
The diameter of a circle?
The diameter of a circle is a straight line going from one point on the circumference (the boundary) of the circle, through the centre of the circle, to another point on the circumference.
Does a tangent circle pass through the center of the circle?
If the tangent circles are outside of one another, then neither passes through the center of the other. If one circle is within the other, then the inner tangent circle might contain the center point of the larger circle. There will be infinitely many inner tangent circles that do not.
What defines a chord in geometry?
A chord is a straight line that extends from one point of the circumference of a circle to another point on the circumference and the diameter of a circle is its largest chord
What is one relationship between lines and circles?
A straight line touches the circumference of a circle only at one point and it is a tangent line
Why circles has no angles and edges?
A circle has no angles because its circumference is a path tyraced put by a point moving at a constant distance from the centre, and an angle is defined as the junction of two straight lines. A circle has one edge - its circumference.
What are circles dimensioned by?
there are 3 measurements of a circle the diameter, which is the distance from one point of the circle through the center point to the other side the radius, which is the distance from the center point to any point of the circle (which is 1/2 of the diameter) and the circumference, which is the distance from one point on the circle all the way around to the point you started at
What is a circle inside a circle called?
A circle inside another circle is called a concentric circle. This means that the circles share the same center point, with one circle contained entirely within the other.
What is the difference of diameter and meter?
The diameter is a straight line going from a point on the circumference of a circle, through the centre of the circle, to another point on the circumference. It can be of any length. A metre is a standard unit for measuring length.
What is the span of the compass in drawing a circle through one point given the center at another point?
It is the distance between the two points.
Locus of a point equidistant from two concentric circles?
Another circle midway between the originals.
What is pi radius and diameter?
The radius of a circle is the distance from the center to any point on the circle. The diameter is twice as much; it is the length of a line segment from one point on a circle to another point on it that passes through the center. Pi is a constant, equal to approximately 3.1416 (the exact value is irrational), which is defined as the ratio of the circumference of any circle to its diameter (all circles are similar so the ratio is always the same).
How many radii does a circle have?
A radii is just a plural form of radius. A circle doesnt have one radius. The term radii is mostly used when talking about multiple circles.
