Properties of a circle geometry
WebSep 15, 2024 · An inscribed angle of a circle is an angle whose vertex is a point A on the circle and whose sides are line segments (called chords) from A to two other points on the circle. In Figure 2.5.1 (b), ∠A is an inscribed angle that intercepts the arc ⏜ BC. We state here without proof a useful relation between inscribed and central angles: Theorem 2.4 WebThe basic properties of a chord are as follows: The chord divides a circle into two segments: major segment and minor segment. A perpendicular line bisects the chord if drawn from the center of the circle to the chord. Two equal chords have two equal angles subtended at the center of the circle.

WebA circle is the same as 360°. You can divide a circle into smaller portions. A part of a circle is called an arc and an arc is named according to its angle. Arcs are divided into minor arcs (0° < v < 180°), major arcs (180° < v < 360°) and semicircles (v = 180°). The length of an arc, l, is determined by plugging the degree measure of the ...
