Polygons and Coordinate Grids Here is an article about coordinate grids and polygons. Polygons must have three sides or more to be a polygon. They also must be a closed figure. A few examples of polygons are: square, triangle, trapezoid, rhombus, rectangle octagon, and hexagon. There are a lot more polygons than I just explained. Poly gons are a very common shape. They are everywhere!
Coordinate grids can show where something is. If you draw a polygon on a coordinate grid, you could locate it by looking at it's position. A coordinate grid is kind of like a map. A coordinate grid is great! Next are different types of triangles. The isoceles triangle has two equal sides. The equilateral triangle has all even sides.
A right triangle has one right angle. That's all about polygons and coordinate grids!
