# Plane Geometry

If you like drawing, then geometry is for you!

Plane Geometry is about flat shapes like lines, circles and triangles ... shapes that can be drawn on a piece of paper |

Hint: Try drawing some of the shapes and angles as you learn ... it helps. |

## Point, Line, Plane and Solid

A Point has no dimensions, only position

A Line is one-dimensional

A Plane is two dimensional (2D)

A Solid is three-dimensional (3D)

Plane Geometry is all about shapes on a flat surface (like on an endless piece of paper).

Quadrilaterals (Rhombus, Parallelogram, etc)

Rectangle, Rhombus, Square, Parallelogram, Trapezoid and Kite

### Polygons

A Polygon is a 2-dimensional shape made of straight lines. Triangles and Rectangles are polygons.
