Answer:
how do you describe the radius, diameter, and a chord?
The radius of a circle is any line segment connecting the centre of the circle to any point on the circle. The chord of a circle is a line segment joining any two points on the circle. The chord of a circle which passes through the centre of the circle is called the diameter of the circle.
how about the semicircle, major arc, minor arc?
A chord, a central angle or an inscribed angle may divide a circle into two arcs. The larger of the two arcs is called the major arc. ... A semi-circle is associated with half of a rotation which is 180°. Minor arcs are associated with less than half of a rotation, so minor arcs are associated with angles less than 180°.
inscribed angle and central angle?
An inscribed angle is an angle formed by two chords in a circle which have a common endpoint.
A central angle is any angle whose vertex is located at the center of a circle. A central angle necessarily passes through two points on the circle, which in turn divide the circle into two arcs: a major arc and a minor arc. The minor arc is the smaller of the two arcs, while the major arc is the bigger. We define the arc angle to be the measure of the central angle which intercepts it.
