## What is the difference between plane triangle and spherical triangle?

Just as you can define a triangle on a planar surface, you can define a triangle on the surface of a sphere. A planar triangle is the shape which connects three points by the shortest route (along straight lines). In the same way, a spherical triangle connects three points by the shortest route.

## What is a plane trigonometry?

Plane trigonometry deals with the relations between the angles and sides of triangles of which the three vertices are located on the surface of a plane and the sides are straight lines (a straight line being the shortest connection between two points on the plane).

## What are the different types of trigonometry?

Trigonometric relationships

• There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant and cotangent.
• These six trigonometric ratios are abbreviated as sin, cos, tan, csc, sec, cot.

## What is the difference between the sum of interior angles of plane triangle and spherical triangle?

Also, the difference between the sum of angles in a plane triangle and spherical triangle is only one second (1″) for a triangle at the earth’s surface having an area of 195 square kilometer.

## Which is the king of all subjects?

## Which is the queen of mathematics?

Carl Friedrich Gauss one of the greatest mathematicians, is said to have claimed: “Mathematics is the queen of the sciences and number theory is the queen of mathematics.” The properties of primes play a crucial part in number theory. An intriguing question is how they are distributed among the other integers.
