Polygon Notes
The document defines and classifies polygons based on the number of sides. It explains that a polygon is a closed plane shape with 3 or more straight sides. Common polygons are then named and defined based on their number of sides, from triangles with 3 sides to dodecagons with 12 sides. Formulas are provided for calculating the sum of interior angles, area of regular polygons, and the sum of exterior angles of any polygon.
Geo 3.5 polygons_notes
This document defines and describes different types of polygons. A polygon is a flat shape formed by three or more straight line segments that are connected and do not intersect except at endpoints. Polygons are named based on the number of sides, such as triangles having 3 sides, quadrilaterals having 4 sides, and pentagons having 5 sides. Polygons can be either convex, where the interior angles add up to more than 180 degrees, or concave, where at least one interior angle is greater than 180 degrees. Special types of polygons include equilateral, equiangular, and regular polygons which have consistent side lengths, interior angles, or both.

Dissection Of The Dodecahedron
The document summarizes the dissection of a dodecahedron into its constituent parts. A dodecahedron is a polyhedron with 12 pentagonal faces. Upon dissection, it is broken down into 63 smaller geometric shapes called "dices". There are 20 corner pieces, 12 face pieces, 30 edge pieces, and 1 core piece. The corner pieces each contribute a facet to 3 faces. The face pieces each correspond to 1 pentagonal face and include 7 facets. The edge pieces contribute facets to 2 adjacent faces. The core piece is a smaller dodecahedron located in the center.

This document discusses geometry concepts related to shapes and sizes. It covers polygons, triangles, and their various parts and classifications. The document is divided into lessons that define polygons and regular polygons, differentiate between convex and non-convex shapes, identify the basic and secondary parts of triangles, and classify triangles based on sides and angles. Multiple choice questions are provided throughout to test the reader's understanding.
1234_POLYGONS-NAMINGPOLYGONSACCORDI.pptx
This document discusses polygons and contains the following information:
1. It defines what a polygon is and lists some of its key characteristics like being a closed figure formed by three or more line segments.
2. It provides examples of different types of polygons classified by the number of sides like triangles, quadrilaterals, pentagons, etc.
3. It asks the reader to identify polygons in examples and classify shapes as convex or concave polygons.
Obj. 42 Solid Geometry
This document defines key terms and concepts in solid geometry, including:
- Classifying three-dimensional figures according to their properties like faces, edges, and vertices.
- Using nets and cross sections to analyze three-dimensional shapes.
- Common solids like prisms, pyramids, cylinders, and their properties.
- Euler's formula relating the number of vertices, edges, and faces in a polyhedron.
- The five Platonic solids - regular polyhedra with faces of identical regular polygons.
