In general, no ... only if the two points are on the equator.
The Mercator is probably the worst possible projection on which to try and identify
great-circle routes and distances, true directions, and true sizes or shapes of anything.
A tangent is always perpendicular to the radius of a circle. A radius is a straight line going from the center of the circle to the circumference (edge) of the circle. A tangent is a straight line outside the circle that touched the circle at one (and only one) point. When a tangent touches the outside edge of the circle at the same point where a radius touches the edge of the circle, the angle between the radius and tangent line is 90 degrees meaning they are perpendicular.
No. A rhombus has four equal straight sides. A circle has no straight parts.
Radius is the shortest distance via straight line between the center point of the circle and its perimeter. Diameter is the greatest distance via straight line from one perimeter of the circle to the opposite perimeter. Diameter = 2x Radius.
A straight line touching the circumference of circle at one point is a tangent

No. A straight line on a mercator map is a path of constant bearing, but this will not generally be a great-circle route.
The great circle chart is a type of navigational projection known as an orthographic projection. It displays the Earth's surface as if projected onto a flat plane from an infinite distance, resulting in great circles appearing as straight lines. This projection is useful for plotting and navigating along the shortest route between two points on the Earth's surface.
Navigators use a Mercator projection chart to plot great circle routes. This chart allows them to draw a straight line, which represents the shortest distance between two points on a curved surface such as the Earth. By following this route, ships and planes can save time and fuel compared to following a rhumb line route.
The Mercator projection is commonly used for navigation and general-purpose world maps due to its ability to accurately represent directions. The Gnomonic projection, on the other hand, is often used for navigational purposes like plotting great circle routes or representing shortest paths between two points on a globe.
The Mercator projection distorts the size of land masses at high latitudes, making them appear larger than they actually are. In comparison, Goode's projection seeks to minimize distortion across the entire map by breaking up the globe into sections and rearranging them to show a more accurate representation of the Earth's surface area.
Airline pilots typically use the Mercator projection for navigation purposes. This projection preserves angles and straight lines, making it useful for plotting flight paths accurately. However, it distorts the sizes of land masses at higher latitudes.
A circle. However, a way of showing a sperical object on a flat surface, such as a map of the world, is called a projection. The most widely used example is the "Mercator Projection", the familiar classroom World map, although there are many others.
If they are in the same plane then it is the length of the straight line joining them. If they are not in a plane then things get complicated. On the surface of the earth (a sphere), the shortest distance is an arc along the great circle. The great circle is a circle whose centre is the centre of the earth and which passes through the two places. This is why New York to Tokyo flights go over the Arctic region. With polyhedra, one way to find the shortest distance is to mark the two points on a net the shape. If you can draw a straight line between the points such that all of it is on the net, then that is the shortest distance. You may need to play around with different nets.
The great circle route is the shortest route.It is just that if you plot a great circle path on a flat map (unless it is the equator or a line of longitude) it will look bent - this is an artifact of map projection.The actual difference in route lengths depends on the routes you are comparing.---------------------------------------------------------------------------------------The great circle route is the shortest route between two locations on a "roughly" spherical object like the earth. It is in effect the straight line between two locations along the surface of a sphere.By the straight route - I assume you mean a straight line on a 2D map. This usually does not coincide with the great circle route. The difference in length between a so-called straight route and a great circle route would then vary based on both the map projection selected and the location of the two endpoints of the journey.-----------------------------------------------------------------------------The SHORTEST line between two points on a sphere IS a GREAT CIRCLE.Also, by definition, the shortest line between two points IS the straight route.
A line is straight and never-ending. A circle curves and is round.
No. No part of a circle is straight.
A straight route is the path taken in a straight line while the shortest distance between two points on a circle is known as the great circle route. However, while travelling the great circle around the globe, the path ahead will look like the straight route.
