what is this
a) sector b) chard c) diameter
d) segment
Answers
a) To recall, a sector is a portion of a circle which is enclosed between its two radii and the arc adjoining them. For example, a pizza slice is an example of a sector which represents a fraction of the pizza. There are two types of sectors, minor and major sector.
b) A chord of a circle is a straight line segment whose endpoints both lie on the circle. ... More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse. A chord that passes through a circle's center point is the circle's diameter.
c) The diameter is the length of the line through the center that touches two points on the edge of the circle.
d) Segment (of a Circle) A segment is a region bounded by a chord of a circle and the intercepted arc of the circle. A segment with an intercepted arc less than a semicircle is called a minor segment. A sector with an intercepted arc greater than a semi-circle is called a major segment.
