Introduction
In this book you will find five shapes, the facts on them and, much more. The 6th grade math class of Hebron Academy Middle School are making these books. We have been assigned five shapes and this book is being made with the help of Ms.G and Mr. Crofton. I hope you enjoy this educational book about shapes!

Equilateral Triangle Overview An equilateral triangle is a three sided figure that is closed. All of the sides are equal and all three angles are the same.
Facts: ✴ Three equal sides ✴All of the angles add up to 180 degrees ✴All angles are 60 degrees ✴Has three vertices ✴It’s a polygon Page 2

✴Four sides
Rhombus
Overview A rhombus is sometimes called a diamond. It is a common shape but not as common as a square or rectangle. Facts: ✴A square is a rhombus but, a rhombus is not a square ✴Opposite angles are equal ✴Four sides ✴Four vertices ✴A polygon and a quadrilateral Page 4
Pentagon Overview A Pentagon is a not so common shape. It has five sides that are all equal. It has five vertices and all the sides are closed.
Facts: ✴A polygon ✴Five sides ✴Five vertices ✴Not all sides are equal ✴Five diagonals Page 5
Non-Polygon Facts: ✴The lines intersect somewhere else besides the vertex ✴Non polygons are not always closed ✴Some sides are not connected ✴This shape has four vertices ✴This shape has no diagonals
Overview This shape is not a polygon because it intersects in places other than the vertices. This is a six sided shape that looks like an hourglass
