How many corners does a sphere have?
A sphere has no corners, it is a 3-D circle.
How many vertices does a sphere have?
A sphere has no vertices. It also has no edges.
How many right angles does a sphere have?
None. A sphere does not have any angles.
What is the relation between sphere and cone?
The ancient Greek mathematician Archimedes proved that the volume of a sphere is four times that of the cone with base equal to a great circle of the sphere and height the radius of the sphere. Maybe this is what the poser of the question meant.
How many sides does sphere have?
A sphere has one side. Not tricky! Unless the sphere is hollow, which would have two sides, inside and outside.
How many right angles are formed by the intersection of two perpendicular great circles on the surface of the sphere?

Are all parallels great circles?
No, not all parallels are great circles. A great circle is the largest possible circle that can be drawn on a sphere, and it divides the sphere into two equal hemispheres. Parallels, or lines of latitude, are circles that run parallel to the equator, and only the equator itself is a great circle. Other parallels, such as those near the poles, are smaller circles and do not divide the sphere into equal halves.
Which parallel of latitude are great circles?
All parallels of latitude, except for the Equator, are not great circles. Great circles are the largest circles that can be drawn on a sphere and pass through its center, whereas small circles do not pass through the center of the sphere.
How to draw great circles and small circles drawn?
To draw a great circle on a sphere, start by defining the diameter as the largest circle that can be drawn on the sphere's surface. For small circles, choose a point on the sphere and draw a circle with that point as the center and the radius less than the sphere's radius. Remember that the center of a small circle lies outside the circle on a sphere's surface.
Why diametrically opposite lines of longitude and equator are called great circles?
A 'great circle' is any circle on the surface of a sphere that has its center at the center of the sphere. The equator is the only parallel of latitude that's a great circle. Every meridian of constant longitude is a semi-circle, and together with the one directly opposite it, they form a great circle. The shortest distance between two points on a sphere is the piece of the great circle through them.
Why is a great circle used for navigation?
Because any 'Great Circle' is the shortest distance across a sphere. Where the Earth is concerned , all the meridians and the Equator are Great Circles. The Plane of a 'Great Circles ' 'cut' the sphere into two equally sized hemispheres. NB Other than the Equator all the latitudes are NOT great Circles.
What is difference between great circle and small circle?
A great circle is a circle on the surface of a sphere that has the same center as the sphere, while a small circle does not share the same center as the sphere. Great circles have the largest circumference of all circles on a sphere, whereas small circles have smaller circumferences. The equator is an example of a great circle on Earth, while lines of latitude other than the equator are examples of small circles.
Why are lines of latitude and longitude called great circles?
They're not. A "great circle" is a circle drawn on a sphere that has its center at the center of the sphere. -- The only line of latitude that's a great circle is the equator. None of the others are. -- Each meridian of longitude is 1/2 of a great circle. In order to form a complete great circle, you have to glue it together with the other meridian of longitude that's directly opposite it on the other side of the globe. Like the Prime Meridian and 180° longitude, or 34° east longitude and 146° west longitude.
Is a sphere made of a rectangle and two circles?
no, a sphere is a ball.
What are 3d circles called?
a sphere
Can you make a closed figure with 2 lines?
On a sphere, two great circles will form a biangle, a polygon with two sides.
What is the mathematical definition of great circle?
A great circle is defined as the largest possible circle that can be drawn on a sphere, resulting from the intersection of the sphere with a plane that passes through the sphere's center. It represents the shortest path between two points on the surface of the sphere, making it significant in navigation and geography. Examples of great circles include the equator and the longitudinal lines on a globe.
