Is a straight line between two points on Mercator Projection a great circle route?

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.

What happens between a radius and a tangent in a circle?
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.
What is difference between a radius and a diameter?
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.
Is a circle a rhombus?
No. A rhombus has four equal straight sides. A circle has no straight parts.
Is the circle or straight line on?
A straight line touching the circumference of circle at one point is a tangent
How many line segments does a circle have?

Mercator projection maps are used to determine great-circle routes?
No. A straight line on a mercator map is a path of constant bearing, but this will not generally be a great-circle route.
Which projection is the great circle chart?
A Great Circle is the largest circle that can be drawn on any sphere. Mercator's Chart projection is the great circle chart.
How are the Mercator projection and the Goode's projection different?
The Mercator projection is used for world maps, and is most accurate between 30 degrees north and south latitude. The further away you go from there, the more exaggerated it becomes. The equal-area projection is also used for world maps, but only represents the continents in equal area with respect to their size, but not location. The conic projection is used for maps that show polar regions, such as Alaska. Imagine an ice-cream cone turned upside down and placed on top of a ball. The only accurate representation would be only in the circle that cone touches the ball.
A way of showing a round surface on a flat surface is called a what?
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.
What is shortest distance between two points?
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.
How much shorter is the great circle route then the straight route?
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.
What is difference between circle and line?
A line is straight and never-ending. A circle curves and is round.
Is a circle straight?
No. No part of a circle is straight.
Compare a straight route with a great circle route?
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.
Where is the equator in a polar projection?
A polar projection of the earth shows a pole (north or south, depending on the projection) at the center of a circular map. The equator is the circumference of the circle.
What kind of projection exhibits a circle as an elliptic shape?
Isometric~!!
Symbol for first angle projection?
