## What is a great circle Class 9 ICSE?

Answer: A great circle is any circle that divides the earth into a circumference of two equal halves.2020-08-27

## What do the terms great triangle and great circle mean?

The triangle formed by joining the ground points A, B and C is called the great triangle, while the circle passing through these pointy is known as the great circle. Lehmann’s Rules: (i) The distance of the point p from each of the rays Aa, Bb and Cc is in proportion to the distance of A, B and C from P respectively.

## What is a great circle route and why is it important?

Planes travel along the shortest route in 3-dimensional space. This route is called a geodesic or great circle. While map projections distort these routes confusing passengers, the great circle path is the shortest path between two far locations. This is why pilots fly polar routes saving time and distance.2021-10-29

## What is the great circle Class 6?

Great circle: The Equator is known as the great circle, as it is the largest circle that can be drawn on the globe. This is because the equatorial diameter of the Earth is the largest.

## What do you mean by triangulation in surveying?

Triangulation is a surveying method that measures the angles in a triangle formed by three survey control points. Using trigonometry and the measured length of just one side, the other distances in the triangle are calculated.

## What is a great circle Class 5?

A great circle is a circle that is drawn on the surface of a sphere (such as Earth) that has a radius equal to the radius of the sphere, and whose center is also the sphere’s center. The Equator is the only latitude that is a great circle. All longitudes are a part of a great circle.2022-01-25

## What is great circle for kids?

Great Circle provides evidence-based, individualized education and therapy services for children, teens and young adults with autism.

## What is great triangle in surveying?

In the 1820s Carl Friedrich Gauss carried out a surveying experiment to measure the sum of the three angles of a large triangle. Euclidean geometry tells us that this sum is always 180º or two right angles.2014-07-10

## What is meant by great circle route?

great circle route, the shortest course between two points on the surface of a sphere. It lies in a plane that intersects the sphere’s centre and was known by mathematicians before the time of Columbus.

## Is also called great circle?

A great circle, also known as an orthodrome, of a sphere is the intersection of the sphere and a plane that passes through the center point of the sphere. A great circle is the largest circle that can be drawn on any given sphere.

## Which is called the great circle?

A Great Circle is any circle that circumnavigates the Earth and passes through the center of the Earth. A great circle always divides the Earth in half, thus the Equator is a great circle (but no other latitudes) and all lines of longitude are great circles.

## What is meant by great circle?

A great circle is the largest possible circle that can be drawn around a sphere. All spheres have great circles. If you cut a sphere at one of its great circles, you’d cut it exactly in half. A great circle has the same circumference, or outer boundary, and the same center point as its sphere.
