Interactive Booklet Polygon One example Your Turn What is a polygon A polygon is a closed plane figure made by line segments Quadrilateral One example . Section 13.1: . Polyhedra. and other Solid Shapes. Basic Definitions. A . polyhedron. is a closed, connected shape in space whose outer surfaces consist of polygons. A . face. of a polyhedron is one of the polygons that makes up the outer surface. Mackenzie Simonsen. Polygons. Triangle- A plane figure with three straight sides and three angles. A way to remember a triangle is that . tri- . means three and a . tri. angle has three sides. . Quadrilateral- A plane figure with 4 straight sides and 4 angles. A way to remember is that . 12.1 and 12.3. Describe Plane Shapes and . Identify Polygons. Lesson Opening. In your math notebook describe (using words) the two shapes below.. Plane Shapes. Both of these shapes are. PLANE SHAPES. 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. . St Paul’s Geometry Masterclass I. Who are we?. Mairi Walker. Final year maths PhD student at The Open University. Studying links between geometry and numbers. A. lso interested in the history of maths. Created By: 2BrokeTeachers. A Parade of Four-Sided Polygons. Quadrilaterals. There are many different types of quadrilaterals. We identify quadrilaterals using their sides and angles. . Side. Angle. Let’s Review…. Grade 9 Math. Visualizing and modeling .

Let’s Review…. What is a polygon?. Closed figure. At least 3 sides. Line segments are sides. Sides meet is call a vertex. More Polygon Terms. Diagonal – connects two non consecutive vertices. Concave – at least one diagonal outside polygon, dented in. A Parade of Four-Sided Polygons. Quadrilaterals. There are many different types of quadrilaterals. We identify quadrilaterals using their sides and angles. . Side. Angle. Let’s Review…. All polygons are made up of line segments and angles. The line segments that create quadrilaterals will be parallel, perpendicular, OR intersecting.. Using Game Theory to Investigate Segregation in Society. Parable of the Polygons. “. Parable of the Polygons. ” is a website which uses apps to explore how areas of cities can become segregated. . Classifying Polygons. Students . will be able . to:. Identify the 2-dimensional shapes based on their properties.. Key Vocabulary. Polygons. Triangles. Quadrilaterals. Pentagons and Hexagons. Other Polygons.
