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 GeometryFor each vector, the angle of the vector to the horizontal must be determined. Using this angle, the vectors can be split into their horizontal and vertical components using the trigonometric functions sine and cosine. The horizontal components for the vectors are solved separately from the vertical. The combined horizontal and vertical components are solved using the Pythagorean theorem to reach the final answer.
Full Answer >Two rays that meet at a common endpoint are called an angle in geometry. In an angle, the rays are its sides and the endpoint is the vertex.
Full Answer >To find the area of a sector, divide the angle of the sector by 360 degrees, then multiply the answer by pi and the square of the radius. You need to know the angle and radius of the circle. A ruler, a calculator and a protractor are helpful in this task.
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.
