What is the circumcenter of a triangle?
Circumcenter - the center of the circle that circumscribes the triangle, ie. goes through all its vertices.
The relationship between triangles and circles?
The three vertices of the triangle uniquely determine a circle that circumscribes the triangle. The three sides of the triangle uniquely determine the circle that inscribes the triangle.
How do you find the perimeter of a circle with triangle inside?
The same as a circle without a triangle inside: multiply twice the radius of the circle (which is its diameter) by π. However, if you have been given some information about the triangle (such as its three lengths or two lengths and one angle, or one length and two angles, or one angle and the length of the side opposite it) which the circle circumscribes, then you can calculate twice the radius of the circle: If you know one side (a) and the angle opposite it (a), then twice the radius of the circle can be found using the sine rule and is given by: 2R = a / sin A → circumference of the circle = aπ / sin A If all you have is the lengths of the three sides, you can calculate the size of one of the angles A (with side a opposite it and sides b & c the other two sides) by the cosine rule and then use the above: A = arc cos ((b² + c² - a²) / (2bc)) → circumference = aπ / sin (arc cos ((b² + c² - a²) / (2bc)))
What is the circumfrance of a triangle?
Never come across "circumfrance". The word circumference is normally used in the context of a circle or circular objects, not polygons. However, by extending the definition, the circumference of a triangle can be interpreted as its perimeter, which is the sum of the lengths of its three sides.
Why is it called circumcenter?
The circumcenter of a triangle is the center of a circle circumscribed around a triangle with each of the vertices of the triangle touching the circumference of the circle.

What is the circumference of a triangle?
triangle does not have a circumference, a circle has a circumference. A triangle only has a hypotenuse (Pythagoras sort of stuff). The circumference of a circle is the perimeter of it, so, perhaps, if your teacher ask for the circumference of a triangle he/she might mean the perimeter of the triangle.

The circumcenter of a triangle is the center of the circle inscribed in the triangle?
The circumcenter of a triangle is the center of the circle drawn outside the triangle with all three vertices touching its circumference.
What is the circumference of a triangular prism?
Well, a triangle isn't a circle, so you cant find the circumference of it.
How is a triangle different from a circle?
A triangle is made from 3 joined line segments whereas a circle has no line segments around its circumference
What is a characteristic of the circumcenter of a triangle?
equidistant from the vertices
How do you calculate length of a circle?
not sure There are two main lengths that are pertinent to a circle, namely, the diameter of the circle and its circumference, the phrase "length of a circle" does not convey much meaning.
What is the parallel of latitude that circumscribes the polar tundra zone?
The Arctic Circle
