1 day ago · Basic Properties. The fundamental definition of a rectangle is as follows. A rectangle is a quadrilateral whose interior angles are all equal. Since the sum of the interior angles of a polygon is 360^\circ 360∘, it follows that each of the interior angles is a right angle. Property 1.

19 hours ago · Definition: Parallel and Perpendicular Planes. Two distinct planes are parallel if they have parallel nonzero normal vectors, which means that they have no points of intersection. Two planes are perpendicular if their normal vectors are perpendicular.
4 days ago · Cartesian coordinates, system of describing the position of points in space using perpendicular axis lines that meet at a point called the origin. Any given point’s position can be described based on its distance from the origin along each axis. Named after French philosopher and mathematician René.
n — Unit vector perpendicular to both a and b, determined by the Right Hand Rule. Right Hand Rule: Position your right hand so that your index finger points along vector a and your middle finger points along vector b: your thumb shows the direction of the cross product a × b.
1 day ago · The moment of inertia about an axis perpendicular to the movement of the rigid system and through the center of mass is known as the polar moment of inertia. Specifically, it is the second moment of mass with respect to the orthogonal distance from an axis (or pole).
5 days ago · We can solve the condition of two lines being perpendicular in 3-D space. We can use the concept of multiple of their slopes being −1 − 1 or we take their vector form to use the dot product on them. Depending on what form the lines' equations take on, you need to find an (x, y, z) ( x, y, z) point that's on both lines.
