How is a chord different from a radius?
A chord touches two points on the circumference of a circle whereas a radius touches only one point from its center.
Is the radius of a circle a chord also?
No. A chord is a straight line joining two points on the circumference of a circle whereas a radius joins only one point on the circumference to the circle centre. A diameter is a straight line joining two points on the circumference (via the circle's centre) and so is also a chord. (Yes, but the question is about a radius, not a diameter!)
What happens between a radius and a tangent in a circle?
A tangent is always perpendicular to the radius of a circle. A radius is a straight line going from the center of the circle to the circumference (edge) of the circle. A tangent is a straight line outside the circle that touched the circle at one (and only one) point. When a tangent touches the outside edge of the circle at the same point where a radius touches the edge of the circle, the angle between the radius and tangent line is 90 degrees meaning they are perpendicular.
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 it called when a line goes halfway across a circle?
The radius of a circle is one half of the circle's diameter, any line going from the center of the circle to the circle itself. A line connecting other points on a circle (or on any curve) is called a chord.
If a radius of a circle intersects a chord then it bisects that chord?
If radius of a circle intersects a chord then it bisects the chord only if radius is perpendicular to the chord.
Can a chord be a radius?
Assuming that the question was meant to be about a chord (not chrod) and radius (not radious), the answer is no. A chord is a line joining two points on the circumference of a circle. One end of a radius is on the circumference but the other is at the centre.
How is a chord different from a radius?
A chord touches two points on the circumference of a circle whereas a radius touches only one point from its center.
Is it possible for a chord of a circle to be the same length as the radius of the same circle?
yes i thinkso because the chord only suppose to have a point in the cente and a radius is like an oval it have 2 end point
Is the radius of a circle a chord also?
No. A chord is a straight line joining two points on the circumference of a circle whereas a radius joins only one point on the circumference to the circle centre. A diameter is a straight line joining two points on the circumference (via the circle's centre) and so is also a chord. (Yes, but the question is about a radius, not a diameter!)
If any two chords are perpendicular do they bisect each other?
Only when one of them is the circle's diameter which is the circle's largest chord.
Does a tangent to a circle intersect the circle in 2 points?
No, only at one point, perpendicular to the radius

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 the relationship between angles and circle?
Angles are like 90˚ and 180˚. A circle is a circle.... "O" <=====this.. So, the only relationship I can guess is that angles can be created inside and outside of the circle. One such example can be a chord and a diameter touching each other at one end. Or a chord and a radius.. Or a radius and another radius. Hope this helps.
A line touching an arc or circle at only one point perpendicular to the arc's radius is said to be?
tangent
What is it called when a line goes halfway across a circle?
The radius of a circle is one half of the circle's diameter, any line going from the center of the circle to the circle itself. A line connecting other points on a circle (or on any curve) is called a chord.
