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. To work out which case you have, use algebra to work out how many points of intersection there are.

How does a line relate to a circle?
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.
What is the difference between circle and line?
is that line is a path through two or more points (compare ‘segment’ ); a continuous mark, including as made by a pen; any path, curved or straight or line can be (obsolete) flax; linen, particularly the longer fiber of flax while circle is (geometry) a two-dimensional geometric figure, a line, consisting of the set of
What is the relationship between line and shape?
A good definition for shape, according to gemoetry is: a shape has two or more point, a line being the simplest. In light of these points, a line is the most basic shape, but shapes can be extremely complex. Several lines can create shapes, such as a square or a triangle.
What is a relationship between lines?
Line Relationships Determine whether the lines are parallel, perpendicular, or neither. Skew Lines Determine whether the lines are skew.
Do circles have lines?
Since there are an infinite number of lines through the center, the circle has an infinite number of lines of symmetry.So a line of symmetry divides the circle into two parts with equal area.
Is a circle one line?
A circle is a plane figure contained by one line, which is called circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference, are equal to one another.
What is the difference between point and circle?
A circle is a simple closed shape. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant. A point in geometry is a location.A point is shown by a dot.
What are the types of lines?
They are:
- Horizontal Lines.
- Vertical Lines.
- Parallel Lines.
- Perpendicular Lines.
Is circle a point?
A point “circle” is just a point; it’s a circle with a radius of zero (hence a degenerate circle). An imaginary circle is one in which the radius is the square root of a negative number—i.e., imaginary.
What is the relationship between lines and shapes quizlet?
What is the relationship between lines and shapes? You create a shape by drawing/painting lines on paper. The edge of a shape implies a line. You just studied 11 terms!
Why are lines and shapes important?
defines the position and direction of a design, image or form.Lines are used to create shape, pattern, texture, space, movement and optical illusion in design. The use of lines allows artist to demonstrate delicacy or force. Curves may take us slowly uphill, or turn sharply twisting our mind as they turn.
What is the difference between shape and form?
In the visual arts, shape is a flat, enclosed area of an artwork created through lines, textures, colours or an area enclosed by other shapes such as triangles, circles, and squares. Likewise, a form can refer to a three-dimensional composition or object within a three-dimensional composition.
What is the relationship between line L and line M?
Line m is in the same plane as line l but does not intersect l (recall that lines extend to infinity in either direction). When lines m and l are both intersected by a third straight line (a transversal) in the same plane, the corresponding angles of intersection with the transversal are congruent.
How do you find the relationship between two lines?
To see whether or not two lines are parallel, we must compare their slopes. Two lines are parallel if and only if their slopes are equal. The line 2x – 3y = 4 is in standard form. In general, a line in the form Ax + By = C has a slope of –A/B; therefore, the slope of line q must be –2/–3 = 2/3.
What is the relationship between line j and line k?
lines k and j are perpendicular. If two lines are parallel, a line that is perpendicular to one of the lines will be perpendicular to the other. This is because when two lines are parallel corresponding angles are equal.
Does a circle have 1 or 0 sides?
A circle has zero sides. A side is a line segment. Every point in a line segment is colinear. A circle is continuously curved.
How many lines is a circle?
So, the diameter acts as a line of symmetry dividing the circle into two parts with equal area. There is an infinite number of lines passing through the center, thus a circle has an infinite number of lines of symmetry.
Is a circle straight or curved?
Circles. A circle is a curved line that runs around a center point. Every part of the curved line is the same distance from the center. A circle can be folded into two halves that are exactly the same, which means that it is symmetrical.
What are circle lines?
Euclid’s definition
A circle is a plane figure bounded by one curved line, and such that all straight lines drawn from a certain point within it to the bounding line, are equal. The bounding line is called its circumference and the point, its centre.
Are Circles real?
A circle is a collection of points equidistant from a fixed center point, and a simple equation can tell us whenever a shape meets this definition.It’s hard to say with certainty whether a perfect circle or a sphere, a circle’s three-dimensional counterpart, exist outside of mathematical abstraction.
