CK Basic Algebra This FlexBook is an introduction to the algebraic concepts of functions, equations, and graphs for middle-school and high-school students. CK Basic Geometry. Written for the beginner student, this FlexBook provides a clear presentation of the essentials of geometry for the high school student.
This FlexBook is an introduction to theoretical probability and data organization. Students learn about events, conditions, random variables, and graphs and tables that allow them to manage data. This FlexBook is a very much improved second edition and provides an introduction to algebraic concepts for the high school student.
CK Geometry — Second Edition. A new second edition, this FlexBook is a clear presentation of the essentials of geometry for the high school student. A new and improved second edition FlexBook, Probability and Statistics Advanced Placement introduces students to topics in statistics and probability, but finishes with the rigorous topics an advanced placement course requires.
A work in progress, CK Earth Science for the high school student covers the study of Earth — its minerals and energy resources, processes inside and on its surface, its past, water, weather and climate, the environment and human actions, and astronomy. CK Biology. CK Biology is a high school FlexBook covering cell biology, genetics, evolution, ecology, microorganisms, eukaryotes, plants, animals, and physiology — it is a work in progress.
CK Chemistry — Second Edition. College Access Readers. CK provides the content and platform for low-cost, mass-customization in textbooks. LPS brings to the table instructional expertise and a real-world incubator for urban education. Together CK and LPS are creating a line of curriculum resources tailored to the most challenging demographic in California and the nation. Key Terms Polygon: Any closed planar figure made entirely of line segments that only intersect at the endpoints.
Side: The line segment making up the polygon. Vertex plural, vertices : The point where the segments intersect. Convex Polygon: A polygon where all the interior angles are less than Interior Angle: The angle inside of a closed figure with straight sides. Concave Polygon: A polygon where at least one interior angle is greater than Diagonal: A line segment that connects two non-consecutive sides of a polygon.
Exterior Angle: The angle formed by one side of a polygon and the extension of the adjacent side. Equilateral Polygon: All sides of the polygon are congruent. Equiangular Polygon: All interior angles of the polygon are congruent. Regular Polygon: A polygon that is equilateral and equiangular. Line segments form the sides of the polygon.
The polygon must also be closed. To name a polygon, the vertices are listed in consecutive order. A polygon lies within one plane. Convex and Concave Polygons In a convex polygon, no section points inward. A side connects consecutive vertices, while a diagonal connects nonconsecutive vertices. A concave polygon has a section that points inward toward the interior of the shape. Concave polygons have at least one diagonal outside the figure the exterior line drawn in the figure below.
Disclaimer:thisstudyguidewasnotcreatedtoreplace yourtextbookandisforclassroomorindividualuseonly. Recall that the interior angles of a triangle adds up to Count the number of triangles and multiply that number by For any equiangular polygon, the measure of each angle is.
Since regular polygons are equiangular and equilateral, this formula can be used for regular polygons as well. Exterior Angles in Convex Polygons The sum of the exterior angles for a convex polygon does not depend on the number of sides.
The sum of the exterior angles of a convex polygon is always Just like triangles, polygons have two sets of exterior angles. Classifying Polygons Polygons can be classified by the number of sides. An n-gon is a polygon with n sides. The table below lists some of the common polygons that have special names.
