6th Grade Geometry Notes PackMr. Thurman’s Math ClassesMy name: __________________________Math Antics- PolygonsPolygon just means a multi-sided shape. Parts of Polygons: _____________________________________________________________________In Greek, the word “polygon” means __________________________________. All polygons are ________________________ shapes, which means the sides are ____________________________ so there are no __________________. Polygons are _________________________________________, or flat shapes. A _____________________ is 2D and closed, but because it is a curved shape, it is NOT a polygon. Special Names for PolygonsNumber of SidesName3Quadrilaterals58OctagonsPolygons are called ________________________________________ if all their angles are equal. Math Antics- PerimeterPerimeter: __________________________________________________________________________________________________________________________________________________________________________Perimeter is a ________-dimensional quality. The ___________________ are really important when talking about perimeter. Perimeter is the ___________________________ distance possible that goes around a shape. To find the perimeter of a polygon, __________ the length of each side, and the total length you end up with is the perimeter. 133350416560Find the perimeter1914525348615P = ________________020000P = ________________10572751847855 cm0200005 cm-4572003702053 cm0200003 cm8763002724154 cm0200004 cm5429252768604 cm0200004 cmFind the perimeter of this regular hexagon1590675317500P = ____________________020000P = ____________________57150241300408622522123406 in.0200006 in.312420013265155 in.0200005 in.27336759550404 in.0200004 in.94297540005010 in. 02000010 in. 314325695325Show and explain how to find the perimeter of this polygon: 6th Grade Math Area of ParallelogramA _______________________________ has 4 sides (is a quadrilateral), and two sets of parallel sides.
