The question is:
Is A radius is an angle that connects to any point on the circle to the center of that circle?
A Radius is a straight line coming from any point of the circle to the center of the circle. And remember that the Diameter is a straight line coming from any point of the circle and going straight through the center to the other side of the circle. The Radius is ALWAYS half of the Diameter; and, the Diameter is ALWAYS twice the Radius.
Full circumference of the circle = (2 pi) times (radius)Arc is a fraction of the full circumference.The fraction is (angle subtended at the center) divided by (360 degrees).If you have the radius 'R' and the angle 'A', the length of the arc is(pi) (R) (A) / 180
Perpindicular lines are like the lines in the letter "T". The intersect each other at a 90 degree angle. A radius is the distance from the center of the circle to the circle itself. It is half the circle's diameter.
the radius
An angle formed by two radius of a circle? I presume that depends on the inclination of one of the two radius related to the other one.
Central Angle An angle in a circle with vertex at the circle's center.
False
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
The relationship between the chord and the radius of the circle is Length of the chord = 2r sin(c/2) where r = radius of the circle and c = angle subtended at the center by the chord
The length of an arc equals he angle (in radians) times the radius. Divide the length by the radius, and that gives you the ange. Measure out the angle on a protractor and draw the length of the radius at the begining and end of the angle. Then draw theportion of the circle with its center at the location ofthe angle and extending out to the radius.

a chord. i took geometry this year. here are some other things that way help. Circle- a set of points that are equidistant from the center of the circle Diameter- a line segment that passes through the center point and has its endpoints on the circle. Radius- a line segment that connects from the center point to the circle Chord- a line segment that has its endpoints on the circle. Arc- a section of the circle's outer points. Semicircle- half of a circle. Central Angle- an angle that has its' vertex as the center point of the circle. Inscribed Polygon- a polygon that has all its' vertexes on the circles outer points. kk :-)

the radius

When the angle is measured in radians arc_length = angle x radius. So, 20cm = angle x 12cm => angle = 20cm / 12cm ~= 1.67 radians
Central Angle An angle in a circle with vertex at the circle's center.
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.
