The exterior of a circle is the set of points in the plane whose distance from the center is greater than the radius.]]> 2019-04-16 16:49:12 UTC https://padlet.com/sshimray/Circle19/wish/352042668 abdulhaq_taniwal9c https://padlet.com/sshimray/Circle19/wish/352051759 An inscribed angle is an angle formed by two chords in a circle which have a common endpoint.
Central angles are angles formed by any two radii in a circle. The measure of the a central angle is equals to twice of an inscribed angle.]]> 2019-04-16 17:11:47 UTC https://padlet.com/sshimray/Circle19/wish/352051759 maria_ariaslozaro https://padlet.com/sshimray/Circle19/wish/352051921 The sector of the circle is shown in as you can see from the figure above, a sector is a pie-shaped part of a circle. The area of a sector can be expressed using its central angle or its arc length.
The segment of a circle is the region bounded by a chord and the arc subtended by the chord.]]> 2019-04-16 17:12:14 UTC https://padlet.com/sshimray/Circle19/wish/352051921 ivan_varenizahw https://padlet.com/sshimray/Circle19/wish/352052776 are circles with a common center. The region between two concentric circles of different radii is called an annulus.
Tangent circles are circles in a common plane that intersect in a single point. There are two types of tangency: internal and external.

A line segment connecting two points on a curve. Example: the line segment connecting two points on a circle's circumference is a chord. When the chordpasses through the center of a circle it is called the diameter.

A secant is a line that intersects a circle in exactly two points. When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.]]> 2019-04-16 17:15:46 UTC https://padlet.com/sshimray/Circle19/wish/352053217 angel_albaochoa4l https://padlet.com/sshimray/Circle19/wish/352053981 A circumscribed polygon is a polygon in which each side is a tangent to a circle. A lesson on polygons inscribed in and circumscribed about a circle. The circumcenter of a polygon is the center of a circle circumscribed about a polygon. ... If a quadrilateral isinscribed in a circle, its opposite angles are supplementary.]]> 2019-04-16 17:17:57 UTC https://padlet.com/sshimray/Circle19/wish/352053981 marcos_pereznunezwu https://padlet.com/sshimray/Circle19/wish/352054286 circumference. The distance around a circle is called the circumference, and although circumference is often used when talking about round things, it can mean a boundary of any shape that completely surrounds something. It's no coincidence that the first part of circumference looks like circle.]]> 2019-04-16 17:18:46 UTC https://padlet.com/sshimray/Circle19/wish/352054286 bryan_barrios_tapiart https://padlet.com/sshimray/Circle19/wish/352056478
A major arc is an arc larger than a semicircle. A central angle which is subtended by a major arc has a measure greater than 180°. A chord, a central angle or aninscribed angle may divide a circle into two arcs. The smaller of the two arcs is called the minor arc.

All lines intersecting the semicircle perpendicularly are concurrent at the center of the circle containing the given semicircle

1. Secant line:A secant is a line that intersects the circle in two different points .
2. Tangent line: A tangent is a line that intersects the circle in exactly one point, called the point of tang ency.
