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 More
The 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.
A prism has a polygonal base and a face opposite and congruent to the base, while a pyramid has a polygonal base and an apex at the opposite side. The edge of the pyramid's base and its apex form a triangle, and the number of sides of its base dictate how many triangular faces are present in the pyramid.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.Full Answer >
The primary difference between a square and a rhombus is a square has four 90-degree angles, while a rhombus does not have any right angles. The sides of a square are perpendicular to one another, unlike the sides of a rhombus.Full Answer >
"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 >
