What type of angle is formed by a tangent and a radius?
The angle between the radius and the tangent is a right angle of 90 degrees.
A part of circle named by its endpoints?
A chord or its radius
Where are the endpoints of a radius?
any point on a circle and the circle's center
Is the tangent of a circle its radius?
No, a tangent is a line that intersects a circle at exactly one point. The radius of a circle is the distance from the center of the circle to any point on the perimeter of the circle.
The angle between a tangent and a radius of a cicle?
90 degree
What does the radius-tangent theorem state?
The radius-tangent theorem is math involving a circle. The radius-tangent theorem states that a line is tangent to a circle if it is perpendicular to the radius of a circle.
What is a theorem about two lines tangent to a circle at the endpoints of a diameter?
Two lines tangent to a circle at the endpoints of its diameter are parallel. See related link for proof.
What is the equation of a circle whose diameter endpoints are at 2 -3 and 8 7 on the Cartesian plane and what are the tangent equations touching its endpoints showing work?
Endpoints: (2, -3) and (8, 7)Centre of circle: (5, 2)Radius of circle is the square root of 34Equation of the circle: (x-5)^2 +(y-2)^2 = 34Slope of radius: 5/3Slope of tangents: -3/51st tangent equation: y--3 = -3/5(-2) => 5y = -3x-92nd tangent equation: y-7 = -3/5(x-8) => 5y = -3x+59
What happens where a radius meets the tangent?
The radius and the tangent are perpendicular at the point on the circle where they meet.
What is the relationship between a tangent line and a radius in a circle?
A tangent line is always perpendicular to the radius.
What is the Radius tangent theorem?
The tangent of a circle always meets the radius of a circle at right angles.
What type of angle is formed by a tangent and a radius?
The angle between the radius and the tangent is a right angle of 90 degrees.
How do you find the radius if you know the endpoints of the diameter?
Radius is 1/2 of the 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.
A part of circle named by its endpoints?
A chord or its radius
Where are the endpoints of a radius?
any point on a circle and the circle's center
If a circle of radius 2 is externally tangent to a circle of radius 8 what is the length of their common tangent?
the length of thr direct common tangent will be 2*{1/2 power of (r1*r2)} the answer will be 8 units in this case...
