All those points for which the distance is equal to that of the radius of a circle lie on the circle. For example points U and V lie on the circle. Semicircle: Semi means half, so semicircle ishalf a circle. It is formed by cutting a whole circle along a line segment passing through...
1. Angles formed by the same arc on the circumference of the circle is always equal. 2. The angle in asemi-circleis always 90°.Central Angle A central angle is the angle formed when two-line segments meet such that one of the endpoints of both the line segment is at the center and...

Segment in a circle: A segment in a circle is the area enclosed by a chord and the associated arc. There are two types of segments: minor segments and major segments. Sector of a circle: A sector is the region enclosed by two radii and the associated arc. The two different sectors of...

A The two radii and the chord form an isosceles triangle.Simplify:Divide by : Therefore, the diagram should look like this:As we saw in question , this portion of the circle is called a "segment," and we find its area by taking the area of the sector minus the area of the triangle...
Thediameterof a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter is twice the radius ord = 2·r. The Greek letter π πrepresents the numberPiwhich is defined as the ratio of the circumference of a circle...
The boundary of a circle is known as its circumference. Important Terms used in Circle Radius (r): The distance of the center from any point on the circumference is called the radius of the circle. Diameter (d): Diameter is a line segment drawn to join any two points on the circumferenc...
In this case, for smooth contours a few segments are sufficient to represent the contours; the more curved it is, the more segments we need and the less compression we get as a result. To handle curved edges, circle arcs are now used in addition to straight lines. Since the choice of ...
