A circle is a collection of points that are equidistant from the center point. It is not a polygon because it does not have three or more sides!

Read more →Rectangles and squares are described together because the formulas for finding their area and perimeter are the same, despite them having a few differences.

Read more →Parallel lines are lines that are always the same distance apart from one another, and no matter how far they are extended, they never cross. Parallel lines have the same slope, and can be drawn in any direction.

Read more →There are five basic types of angles (based on angle measurements), two pairs of angles that have special properties, vertical angles (when angles are drawn by crossing lines), and adjacent angles.

Read more →When you compare two or more shapes, they can be classified as similar (same shape but different size) or congruent (the same shape and same size).

Read more →A triangle is a polygon with three sides. There are several types of triangles which are based either on the length of the sides, or on the size of the angles.

Read more →A three-dimensional (3D) shape has three dimensions: length, width, and height, while a 2D shape has only length and width.
