Parallel is an alternate term for a line of latitude on a map, while meridian is an alternate term for a line of longitude. Lines of latitude are located parallel to the Equator and never intersect, which is why they are also called parallels.
Know MoreThe lines of longitude on a map all intersect with each other at the North Pole and South Pole. They run up and down from the two poles around the globe. Coordinates are measured and read in terms of degrees latitude and longitude. Zero degrees for latitude is the Equator, while zero degrees for longitude is the Prime Meridian.
Learn more about Shapes"Concave" is an adjective describing a surface that curves inward, like the inner surface of a sphere. Its antonym, "convex," describes a surface that curves outward, like the exterior of a sphere. In geometry, concave and convex refer to polygons. A concave polygon has at least one angle greater than 180 degrees. A convex polygon is made of angles each less than or equal to 180 degrees.
Full Answer >A cube is a six-faced, three-dimensional figure composed of square-shaped faces of the same size that meet at 90-degree angles, whereas a cuboid is a box-shaped object made of six faces that all meet at 90-degree angles. A cuboid shape can also be a cube if all sides are the same length, but not all cuboids are cubes. Cubes and cuboids contain eight vertices and 12 edges.
Full Answer >A circle is actually a special kind of ellipse where the two focuses are equal. Every ellipse contains two points called a focus. The perimeter of the ellipse is the group of points, which are equally distant from these two focuses.
Full Answer >The primary difference between a rectangle and a parallelogram is that all angles in a rectangle are 90 degrees, while none of the angles in a parallelogram are required to be 90 degrees. A parallelogram is defined by having opposite sides of equal length, and opposite angles of equal size.
