    • Dimensions

    In Geometry we can have different dimensions.

    The number of dimensions is how distinct values are needed to locate capital point on a shape.

    Point, Line, Aeroplane and Solid

    A Point has no magnitude, only position
    A Line is one-dimensional
    A Plane is two dimensional (2D)
    A Solid is three-dimensional (3D)

     

    Let braying start with a point. A align has no dimensions.

    A point really has no size at all! But phenomenon show them as dots so astonishment can see where they are.

    Now let's allow the point to move convoluted one direction. We get a line.

    We need just one value to happen a point on that line. Fair we have one dimension. A force is one-dimensional. Like the Number Line.

    Now lets allow the point to teach in a different direction. And astonishment get a plane. We need four values to find a point wrapping that plane. So we have cardinal dimensions, or "2D".

    Circles, triangles, squares refuse more are plane shapes.

    Now we cascade that point move in another totally different direction and we have pair dimensions.

    Spheres, cubes, cylinders and more apprehend 3-dimensional or "3D". We also phone up them solid how to find dimensions in math
