draw the parts of a circle and define each part with pictures
Answers
Step-by-step explanation:
A circle is the set of all points in the plane that are the same distance away from a specific point, called the center. The center of the circle below is point A. We call this circle “circle A,” and it is labeled ⨀A.
Important Circle Parts
Radius: The distance from the center of the circle to its outer rim.
Chord: A line segment whose endpoints are on a circle.
Diameter: A chord that passes through the center of the circle. The length of a diameter is two times the length of a radius.
Secant: A line that intersects a circle in two points.
Tangent: A line that intersects a circle in exactly one point.
Point of Tangency: The point where a tangent line touches the circle.
The tangent ray TP−→− and tangent segment TP¯¯¯¯¯¯¯ are also called tangents.
Tangent Circles: Two or more circles that intersect at one point.
Concentric Circles: Two or more circles that have the same center, but different radii.
Congruent Circles: Two or more circles with the same radius, but different centers.
Answer:
radius , diameter, centre and circumference
Step-by-step explanation:
the four main parts of circle are radius, centre, diameter and circumference. the centre is the the mid point of the circle and the radius is the point from centre to the last point of circle. and the diameter is the double of radius. and the circumference would be the arc lenght of the circle and it is the perimeter of a circle or ellipse.
