Circle Definition: a set of all points in a plane at a given distance from a given point (center/origin). Picture:

Radius Definition: The given distance from center/origin of the circle to the edge. Picture:

Diameter Definition: A chord that passes through the origin/center. Picture:

Chord Definition: A line segment whose endpoints lie on the circle. The diameter is the longest chord. Picture:

Tangent Definition: A line that touches (intersects) the circle only once. The point the circle touches the circle is named the point of tangency. Picture:

Semicircle Definition: Half of a circle. Picture:
