There's a simple answer: The earth is a sphere and the parallels are, well, parallel to each other. So obviously the ones closer to the poles are shorter than the ones closest to the Ecuator. As for the meridians all meet at one point ehich are the poles, so they are all the same length.
Meridians and circles of latitude (parallels) will meet at an angle of 90 degrees at the equator only. All other crossings will not be 90 degrees as they converge to the two poles. To correct the previous answer: All meridians crossing parallels are not at 90 degrees due to the curvature of the spherical triangle's three sides. However, they will all cross at 90 degrees as viewed each from a specific point in space which would be perpendicular to the earth's N-S axis and directly over (in line) with the meridian.
A triangle has only three angles and they sum to 180 degrees.
If it has four 90 degree angles, than it's a square, and therfore only has four angles.
The 4 interior angles are: 89, 89, 91 and 91 degrees

On a globe, parallels and meridians do not intersect at right angles; only the equator and the prime meridian intersect perpendicular to each other. On a Mercator projection map, the meridians appear as straight lines converging at the poles, while the parallels are equally spaced horizontally, giving the illusion that they intersect at right angles, when in reality that is not the case.
On a globe, parallels and meridians meet at right angles only at the equator and the poles. On a Mercator projection map, all meridians intersect the equator at right angles, while parallels intersect meridians at right angles throughout the map.

Parallels are lines of latitude that run east-west around the globe, while meridians are lines of longitude that run north-south. Parallels are always equidistant from each other, while meridians converge at the poles. Parallels help locate positions north or south of the equator, while meridians help locate positions east or west of the Prime Meridian.
Parallels, as the name inplies, run parallel to each other in an east-west orientation. Meridians run through both poles, and so cannot be parallel.

Parallels are lines of latitude that run parallel to the equator, while meridians are lines of longitude that run from the North Pole to the South Pole. Parallels measure distance north or south of the equator, while meridians measure distance east or west of the Prime Meridian. Together, parallels and meridians form a grid system used to locate points on the Earth's surface.
Meridians are lines on a sphere (or other geometric solid) all of which go through the poles. Degrees are a unit of measurement of angles and temperature and concentration, and some other things. As a unit for measuring angles, meridians are measured in degrees. There are 360 degrees in a complete circle.
Meridians are imaginary lines that run from the North Pole to the South Pole on a map or globe, helping to indicate longitude. Parallels, on the other hand, are imaginary lines that run parallel to the equator, indicating latitude. Both meridians and parallels are used for navigation and mapping purposes.
The Mercator projection has straight meridians and parallels that intersect at right angles. Scale is true at the equator or at two standard parallels equidistant from the equator. The projection is often used for marine navigation because all straight lines on the map are lines of constant azimuth.
