Polygons. A polygon is a closed figure made of line segments, or sides. Each line segment meets at its endpoint with the next line segment. Basically, if the figure you see has straight sides that are all connected than it is a polygon. A circle is NOT a polygon!.
You can tell how many sides a polygon has by looking at the beginning part of the name of the shape:
Triangle: The beginning part of this word is TRI meaning 3 so a triangle has 3 sides.
A square has 4 sides that are EQUAL in length.
Every square IS a rectangle
All squares have four square corners
A rectangle has 4 sides in which the 2 opposite sides are equal in length.
A rectangle is a parallelogram with four square corners
