is a circle a line?
535253
A circle is a type of line. Imagine a straight line segment that is bent around until its ends join. Then arrange that loop until it is exactly circular - that is, all points along that line are the same distance from a center point.

A "side" usually refers to the sides of a polygon, such as a square or a triangle. Although a circle is a shape, it is not a polygon, so it does not have sides. ... It can't have infinitely many sides because infinity is not a number, and you can't actually have infinity of something.

There are three ways a line and a circle can be associated, ie the line cuts the circle at two distinct points, the line is a tangent to the circle or the line misses the circle.

It is LINE. A straight line, no curves. For example: y = 2x - 3 This is linear because the exponent on x is one.

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no "wiggles" anywhere along its length. ... Consider first lines in a two-dimensional plane.

Perimeter or Circumference. ... The length of a straight-sided shape's outline is called its perimeter, and the length of a circle's outline is called its circumference.

A cone has a circle as its base, a curved face and a point. A cylinder has circular faces at each end and a curved face. A circle is a shape where it is always the same distance from the edge to the centre.

No tangent line can be drawn through a point within a circle, since any such line must be a secant line. However, two tangent lines can be drawn to a circle from a point P outside of the circle. ... By the secant-tangent theorem, the square of this tangent length equals the power of the point P in the circle C.

Since there are an infinite number of lines through the center, the circle has an infinite number of lines of symmetry. When the circle is folded over a line of symmetry, the parts of the circle on each side of the line match up.

1) Draw a number line. ... For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution. For < and >, use an open circle to indicate the number itself is not part of the solution.

In fact a Circle is an Ellipse, where both foci are at the same point (the center). In other words, a circle is a "special case" of an ellipse.

A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. Points that are on the same line are called collinear points. A line is defined by two points and is written as shown below with an arrowhead.

No, a circle is a two dimensional shape. No. The mathematical formula used to describe a circle is an equation, not one function. For a given set of inputs a function must have at most one output.

Tangent to a Circle Theorem: A line is tangent to a circle if and only if the line is perpendicular to the radius drawn to the point of tangency. ... Two Tangents Theorem: If two tangent segments are drawn from the same external point, then the segments are equal.

Lines are strokes connecting two points, and the most basic element of visual design. We can use them to create shapes, and when we repeat them, we can form patterns that create textures. A line connects two points and is the simplest element of design.

Another one of the parts of a circle is a radius, which is a line segment with one endpoint at the center and one endpoint on the circle. Congruent circles have congruent radii (the plural of radius). Concentric circles have the same center.
