If you like drawing, Geometry is for you!
|Plane geometry is all about shapes like lines, circles and triangles ... shapes that can be drawn on a flat surface called a Plane (it is like on an endless piece of paper).|
Point, Line, Plane and Solid
Hint: Try drawing some of the shapes and angles as you learn ... it helps.
A Polygon is a 2-dimensional shape made of straight lines. Triangles and Rectangles are polygons.
