A symmetrical pattern is a pattern in which converging lines form an angle that somewhat resembles an acute angle. When two patterns are symmetrical, one becomes exactly like another when flipped or turned, according to Primary Resources.
Know MoreA common example of symmetry is a reflection. The image of an object looks exactly like the object when turned through an angle of 180 degrees. In geometry, some shapes have lines of symmetry. Such a shape is symmetrical because, when folded along that line of symmetry, it gives two equal halves that look exactly the same. Symmetrical patterns are evident among regular objects, or objects with proportional form.
Learn more about GeometryThe vertex is the common endpoint when two rays intersect to form an angle. The formed angle is named by using three points. One point is on each of the two rays, and the third is at the vertex point.
Full Answer >An orthogonal vector is a vector that is at an angle of 90 degrees, or perpendicular, to another vector. Up to three vectors can be mutually orthogonal to each other in a three-dimensional space.
Full Answer >The common endpoint of the sides of an angle is called a vertex. For example, triangles have three vertices, while squares have four. These common endpoints are often colloquially called corner points, though this may result in confusing them with angles.
Full Answer >An angular unconformity is a geological phenomenon where an older layer of rock sits directly beneath a much younger layer of rock because the older layer was forced up at an angle, eroded, and younger rock deposited on top of it. An angular unconformity only stays constant for a relatively short distance into a rock face. Digging horizontally into the older rock reveals younger angled layers.
