Is the length of the diameter always equal to the length of the radius?
The length of the diameter is always twice the length of the radius.
How many radii does a chord have?
NoneAdditional Information:-Unless it is the diameter of the circle which is its the largest chord then it will have a length equal to two radii (but the chord itself has no radii).
Why do the tangents drawn at the ends of a chord of a circle make equal angles with the chord?
Because in effect an isosceles triangle has been constructed and the base angles are always equal.
What do you call a line segment that divides the circle in two?
It's a chord, unless the 2 parts are equal, when it becomes a diameter.
Is length equal to width?
Not always.
Is a chord always equal to the lenght of the diameter?
No but the diameter is the largest chord in a circle.
Is the length of the diameter always equal to the length of the radius?
The length of the diameter is always twice the length of the radius.
How many radii does a chord have?
NoneAdditional Information:-Unless it is the diameter of the circle which is its the largest chord then it will have a length equal to two radii (but the chord itself has no radii).
What is equal to 10.5 I'm in diameter?
It is equal to a diameter of 10.5 units of length.
Does a diameter that is perpendicular to a chord bisect the chord?
Yes, any diameter which is perpendicular to a chord bisects said chord. This can be proved most easily with a picture, but is proved using a congruent triangle proof. Both triangles include the points at the center of the circle and the intersection of the diameter and chord. The other points should be the endpoints of the chord. They are congruent by hypotenuse leg; it was given that they are right triangle by the "perpendicular", the "leg" is the segment between the center of the circle and the intersection, and it is equal in both triangles because it is the same segment in both triangles. The hypotenuses are equal because both are radii of the circle. Because the triangles are congruent, their sides must be so the two halves of the chord are congruent, and therefore the chord is bisected by the diameter.
What does diamater mean?
The diameter is the chord (line that goes from the circle to the circle) that goes through the center of the circle. It is the largest chord. It is also equal to twice the radius.
Why do the tangents drawn at the ends of a chord of a circle make equal angles with the chord?
Because in effect an isosceles triangle has been constructed and the base angles are always equal.
Does two radii equal one diameter?
That's right. In a circle, the length of a diameter will be the same as twice the length of a radius.
Is the radius always equal to the diameter of a circle?
No, the radius of a circle is always 1/2 of the diameter.
What do you call a line segment that divides the circle in two?
It's a chord, unless the 2 parts are equal, when it becomes a diameter.
Is length equal to width?
Not always.
What are its parts of circle?
Circumference is the perimeter of a circle Diameter is the length spanning a circle cutting through its center Radius is half the length of a circle's diameter Tangent is a straight line that touches a circle's circumference at one point Arc is part of a circle's circumference Chord is a straight line joining any two points of a circle's circumference Sector is the area enclosed by an arc and two radii Segment is the area enclosed by arc and a chord Circle's circumference divided by its diameter is equal to the value of pi Area of a circle = pi*radius squared There are 360 degrees around a circle
