What is a straight line joining points on a circle?
A straight line joining points on a circle is called a "chord" of that circle. If the line happens to pass through the center of the circle, then it's a "diameter" of that circle. The question asked about "points" on a circle, so two points on the circumference of that circle are being considered. (No line can join more than two points of a circle.)
What is the relationship between circle and diameter?
The diameter is the distance across the circle. So if you split the circle in half by drawing a line through it, the diameter would be the length of that line.
How do you construct a line tangent through a circle through a point outside the circle?
The tangent line only touches the outside of a circle at one given point. So an outside line perpendicular to the circle's diameter at 90 degrees should do.
What are symmetery lines?
If you take a circle for example, a line of symmetry is any line that can go through that circle and if you fold the circle in half it will be equal. So a line of symmetry is a line that you divide any shape in half with and have both halves be the same.
What is the formula for Perpendicular Slope?
Line a with a slope perpendicular to that of line b has a slope that is the negative reciprocal of line b's. So basically the negative reciprocal.
How do you drawing a globe?
First draw a round circle. then draw around the circle a line that looks like a bracelet. Next at the bottom of the circle draw a line down. Then underneath that line Make like a thin oval. Last but be sure to do it make line on the circle so it looks like continents.
How many lines are tangent to a circle?
You can have a tangent line for every point on a circle, so the answer is theoretically infinite.
What are the symbols in 'Harry Potter and the Deathly Hallows'?
Picture this. A straight, vertical line (The Elder Wand) . A circle (The Ressurection Stone) is at the based of the line so that the bottom of the circle is touching the bottom of the line, and the topof the circle is rougly halfway up the line. This image is then enclosed in a triangle (The Cloak of Invisibility), so that the top corner is touching the top of the line, the two sidelengths touch the sides of the circle (if that makes sense) and the bottom length touches the bottom of the circle.
What did the line say to the circle?
get off of me i'm a circle not a circle with a line through it
What is a line through a circle that does not go through the center?
A line through a circle that does not go through the center of the circle is a secant line. A line through a circle that does go through the center is still a secant line, by the way. Compare this to a line segment that has its two endpoints on the circumference of the circle. That line segment is a cord of the circle. If that cord of the circle passes through the center of the circle, then the cord is a diameter of that circle.
What is the area of the circumference with a circle of 7 feet?
The circumference of a circle is a line. Because it is a line it has no area, only length. So the area of the circumference cannot exist!
What is the term for a line that meets a circle or arc at only one point on it's exterior so it will not go through the circle?
a tangent to the circle
