Manipulative 1 - Inclination Created with GeoGebra.

An inclination is the angle between a reference line or plane and another line or plane. In manipulative 1, the inclination of the line is respective to the x-axis. Note that the inclination is measured with an angle between 0° and 90° (0° < α ≤ 90°).

An incline is a surface that is sloped relative to the horizontal.

An inclined plane is a plane that is sloped relative to a reference plane. For astronomical objects, the reference plane contains the equator of the object about which another object orbits.

In manipulative 2, the blue ellipse represents a plane containing the equator of a star. The red ellipse represents a plane containing the orbit of a planet.
