Is the circle or straight line on?
A straight line touching the circumference of circle at one point is a tangent
What is a reflection for circumference of a circle?
The reflection in a line will be another congruent circle.
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.
Difference between diameter and circumference?
A diameter is a straight line from one side of a circle, through the centre, to the other side. A circumference is the curved line forming the boundary of a circle.
What is the diameter circumference?
Diameter is the length of a straight line passing through the center of a circle or sphere and connecting two points on the circumference of the circle or the surface of the sphere. Circumference is the length of the closed curve of a circle.
Is the circle or straight line on?
A straight line touching the circumference of circle at one point is a tangent
What fraction of a circle does 7 degrees represent?
It is NOT a fraction but a SECTOR. of 7 degres. The regions of a circle are: - Circumference ; all the way around. Radius ; distance from the centre to the circumference Diameter ; Twice the radius and a straight line from circumference through the centre to the opposite side . Chord; a line drawen inside a circle, betwwen two points on the circumference, but NOT touching the centre. Arc ; that part of the circumference that form the curved side of a sector. Sector ; An area inside the circle whose bondaries are two radii and an arc. Tangent ; a line outside the circle just touching the circumference in ONE place.
How is a tangent different from a chord?
A Tangent is a straight line, outside the circle, that just touches the circle circumference in one place. A Chord is a straight line , inside the circle, but not passing throught the centre. and touches the circle circumference in two place.
How many curved line in a circle?
A circle has one curved line and it is its circumference
Can a chord of a circle also be a diameter of a circle And why?
A chord is a straight line that spans the circumference of a circle and the diameter of a circle is a straight line in a circle spanning its circumference and passing through the circle's centre.
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!
Line touching a circle?
Is a tangent
What is an arc in a circle?
a curved line that is part of the circumference of a circle
What is the straight line which touches the circumference in a circle?
It is the tangent of the circle
You are a straight line that join 2 points on the circumference of a circle?
The name of a straight line joining two points on the circumference of a circle is a chord.If the line passes through the the centre of the circle it is called a diameter
What is a reflection for circumference of a circle?
The reflection in a line will be another congruent circle.
How does the circumference compare to the radius of the circle?
Well the radius is only half of the line on the circle the circumference is all around
