what are the three differences between parallels and meridians?

Meridians are associated with longitudes. -- Parallels are parallel, and no two parallels intersect. ... Every point on a meridian has the same longitude. -- Every parallel in the same hemisphere has a different length.

The converse is also true: if alternate angles are equal, the lines are parallel. The two parallels lines are a constant distance apart, so any pair of lines that intersects them at the same angle will make segments with the same length.

The parallel circles from the equator to the north and south poles are termed as parallels of latitude. As opposed, the lines of reference, running from the two poles is known as meridians of longitude. ... The parallels of latitude are of unequal length, whereas the meridians of longitude are of equal length.

Some characteristics of latitudes: The arc between any two parallels a and b will subtend an angle of (a-b) ° at the centre of the globe. There is a complementary arc between the parallel and the pole subtended by an angle of (90-n) ° at the centre.

All the meridians on Earth are great circles. Meridians, including the prime meridian, are the north-south lines we use to help describe exactly where we are on the Earth. All these lines of longitude meet at the poles, cutting the Earth neatly in half. ... The Equator is the only east-west line that is a great circle.

The diagonals of a parallelogram are not of equal length. They bisect with each other at the point of intersection with equal sides across the point of intersection.

As nouns the difference between east and orient is that east is one of the four principal compass points, specifically 90°, conventionally directed to the right on maps; the direction of the rising sun at an equinox while orient is (orient).

The diagonals of a parallelogram are not equal. ... Because the parallelogram has adjacent angles as acute and obtuse, the diagonals split the figure into 2 pairs of congruent triangles. Since the angles are acute or obtuse, two of the shorter sides of the triangles, both acute and obtuse are congruent.

All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary). All sides are congruent by definition. The diagonals bisect the angles. The diagonals are perpendicular bisectors of each other.

All the meridians on Earth are great circles. ... If you were to cut into the Earth right on its Equator, you'd have two equal halves: the Northern and Southern Hemispheres. The Equator is the only east-west line that is a great circle. All other parallels (lines of latitude) get smaller as you get near the poles.

Properties of a Parallelogram and Distance Formula: The properties of a parallelogram are: (i) The sum of all the angles of a parallelogram is always equal to 360o . (ii) The sum of any two consecutive angles of a parallelogram is 180o . (iii) The opposite angles of a parallelogram are also the same.

In other words, a great circle is locally "straight" with zero geodesic curvature, whereas a rhumb line has non-zero geodesic curvature. Meridians of longitude and parallels of latitude provide special cases of the rhumb line, where their angles of intersection are respectively 0° and 90°.

Parallelogram Theorem #1: Each diagonal of a parallelogram divides the parallelogram into two congruent triangles. Parallelogram Theorem #2: The opposite sides of a parallelogram are congruent. ... You can show that alternate interior angles are congruent and hence lines are parallel for this part of the proof.

Latitude is a measure of how far north or south somewhere is from the Equator; longitude is a measure of how far east or west it is from the Prime Meridian. Whilst lines (or parallels) of latitude all run parallel to the Equator, lines (or meridians) of longitude all converge at the Earth's North and South Poles.

The earth has 360 imaginary lines called longitudes or meridians running vertically between the poles. Each of these longitudes is called a degree. ... The time difference between each longitude (each degree) is 4 minutes. So if it is 12 noon at Greenwich (0 degree), it would be 12:04 pm at 1 degree meridian and so on.

These properties concern its sides, angles, and diagonals. The parallelogram has the following properties: Opposite sides are parallel by definition. ... The diagonals bisect each other.
