PPT-Inscribed & Circumscribed Polygons

Inscribed amp Circumscribed Polygons Lesson 107 A polygon is inscribed in a circle if all of its vertices lie on the circle Inscribed Circumscribed A polygon is circumscribes about a circle if each of its sides is tangent to the circle. IV. All but two of the propositions in this book are constructions to inscribe or circumscribe figures. . Definition . 1. . A rectilinear figure is said to be . inscribed in a rectilinear figure. when the respective angles of the inscribed figure lie on the respective sides of that in which it is inscribed. . ‘ROUND ABOUT. INSCRIBED AND CIRCUMSCRIBED FIGURES. We already know a bit about . _____________.. You know how to find the . _____________.. You know how to find the . _____________. . Using . these, we found the . ‘ROUND ABOUT. INSCRIBED AND CIRCUMSCRIBED FIGURES. We already know a bit about . circles.. You know how to find the . radius.. You know how to find the . diameter.. Using these, we found the . circumference. Construction methods can also be used to construct figures in a circle. One figure that can . be inscribed . in a circle is a hexagon. Hexagons are polygons with six sides.. 1. 1.3.3: Constructing Regular Hexagons Inscribed in Circles. Central Angles. Central Angle. (of a circle). Central Angle. (of a circle). NOT A. Central Angle. (of a circle). A . central angle. is an angle whose vertex is the CENTER of the circle. CENTRAL ANGLES AND ARCS. What will we learn. Parts of a circle including radius, diameter, arcs, angles. How to find arc measures . How to find angle measures. Parts of a Circle. A. B. C. D. Radius. - segment from center . pt. Triangles are not the only figures that can be inscribed in a circle. It is also possible to inscribe . other figures. , such as squares. The process for inscribing a square in a circle uses previously learned skills. BUILDING POLYGONS. We use line segments to build polygons. . A polygon is a closed shape with straight sides.. POLYGON. NOT A POLYGON. POLYGONS. POLYGONS. Polygons may also be called 2D shapes or PLANE FIGURES. .
