How many tangents can be drawn to a circle containing a point inside the circle?
None can. A tangent is a line that touches a circle at only one point. If it wentthrough a point inside the circle, then it would have to touch the circle at twopoints ... one on the way in and another one on the way out.
What is the space inside a circle?
Circumference is the outside of the circle and the inside is the are of the circle. And inside of the circle, there is diameter and radius. Radius is from the center point to the edge of the circle and diameter is all the way across.
What is the Tangent Line to Circle Theorem?
The Tangent Line to Circle Theorem states that a line is tangent to a circle if and only if it's perpendicular to the circle's radius.
What is a line that passes through the center of a circle?
Any line that passes through a circle and touches two points on its circumference is a secant line. (Recall that a line is infinitely long.) If the line passes through the center of the circle, it is still called a secant line. Compare this to a line segment that has its endpoints on the circumference of the circle. That line segment is called the cord of the circle. If that cord passes through the center of the circle, it is a diameter of the circle, which is the longest cord of that circle.
A segment with endpoints on a circle?
A chord is a line segment whose endpoints lie on a circle. A secant is a line (or line segment) that intersects a circle in two places, endpoints NOT on the circle.
Can you make a line segment longer than the diameter of circle?
Not if the whole segment is inside the circle.
How many tangents can be drawen to a circle contaning a point inside the circle?
None. A tangent is a line that has exactly onepoint in common with the circle.If it contained a point inside the circle, then it would have to pass through twopoints on the circle.
What do you called the region consisting of all points which are either on the circle or line inside the circle?
A circular region or a disk.
What if two circles touch each other the one circle is inside the other?
The centres and the point of contact are all in a straight line, if the circle is inside or outside.
Does a zigzag line drawn inside a circle represent a type of switch?
True
How do you play circle of fifths?
You line up whiskey, vodka and rum bottles in a circle, get your friends inside the circle and the last one leaving wins!
How are diameter and cord the same?
A chord is a straight line inside a circle that spans its circumference and the diameter of a circle is its largest chord.
How many tangents can be drawn to a circle containing a point inside the circle?
None can. A tangent is a line that touches a circle at only one point. If it wentthrough a point inside the circle, then it would have to touch the circle at twopoints ... one on the way in and another one on the way out.
What of a circle is a line segment from the center of the circle to any point on the circle?
This describes a chord. A chord is a mathematical term on a part of the circle. A chord uses any 2 points in a circle, not matter if they are away from the diameter line or not, they just have to be inside the circle. If you connect the 2 points you have chosen, it gives you a chord. A chord can look like a line segment. .______. This is a line segment, on the left.
How is a diameter worked out?
A circle has an infinite number if diameters, but they are all the same length. The length of the diameter of a circle is the length of the longest straight line that can be drawn completely inside the circle. If the center of the circle is marked, then it's easy to draw a line that is a diameter ... it's any line that passes through the center of the circle.
The diameter of a circle is always twice the length of the radius?
True !! it is also a straight line from one side of the circle, through the middle point to the other side of the circle. Any other straight line inside a circle, that does NOT touch the centre is a chord.
Is the region enclosed by a circle convex?
No, the region enclosed by a circle is not considered convex because it contains points within the circle that do not lie on the boundary of the circle. In convex regions, any line segment connecting two points inside the region will also lie completely inside the region.
