3 Honors Geometry ircle Investigation ircles irst ircle Name: lock: ate: ircle onjecture #1 The measure of a central angle is the as the measure of the arc it intercepts. O ircle onjecture #2 The measure of an inscribed angle is the measure of the arc it intercepts. ircle onjecture #3 Inscribed angles that intercept the same arc are Second ircle ircle onjecture #4 ngles inscribed in a semicircle are angles.
4 ircle onjecture #5 Opposite angles of a quadrilateral inscribed in a circle are. Third ircle E G ircle onjecture #6 tangent to a circle is to the radius drawn to the point of tangency. ircle onjecture #7 Tangent segments to a circle from a point outside the circle are. ourth ircle O H ircle onjecture #8 Parallel lines intercept arcs on a circle.
5 E G ircle onjecture #9 If two arcs are congruent, then their are congruent. ifth ircle O ircle onjecture #10 If two chords are congruent, then their are congruent. H Sixth ircle ircle onjecture #11 n angle formed by a tangent ray and a secant is always the measure of the arc it intercepts.
6 Seventh ircle ircle onjecture #12 The measure of an angle formed by two intersecting chords is the of the measures of the arcs that are intercepted by it and its vertical angle. ircle onjecture #13 The measure of an angle formed by two secants that intersect outside a circle is of the arcs intercepted by it.
