Can a triangle have two right angles yes or no?
No. A triangle's angles must add up to 180 degrees so it cannot have two right angles. However, the answer is yes if you are talking about a triangle on the surface of a sphere. In this case the geometry is non-Euclidean. If you are staying with standard Euclidean geometry, then the answer no above is correct.
What are some real world applications of geometry?
Euclidean geometry has become closely connected with computational geometry, computer graphics, convex geometry, and some area of combinatorics. Topology and geometry The field of topology, which saw massive developement in the 20th century is a technical sense of transformation geometry. Geometry is used on many other fields of science, like Algebraic geometry. Types, methodologies, and terminologies of geometry: Absolute geometry Affine geometry Algebraic geometry Analytic geometry Archimedes' use of infinitesimals Birational geometry Complex geometry Combinatorial geometry Computational geometry Conformal geometry Constructive solid geometry Contact geometry Convex geometry Descriptive geometry Differential geometry Digital geometry Discrete geometry Distance geometry Elliptic geometry Enumerative geometry Epipolar geometry Euclidean geometry Finite geometry Geometry of numbers Hyperbolic geometry Information geometry Integral geometry Inversive geometry Inversive ring geometry Klein geometry Lie sphere geometry Non-Euclidean geometry Numerical geometry Ordered geometry Parabolic geometry Plane geometry Projective geometry Quantum geometry Riemannian geometry Ruppeiner geometry Spherical geometry Symplectic geometry Synthetic geometry Systolic geometry Taxicab geometry Toric geometry Transformation geometry Tropical geometry
Does a line always have an endpoint?
Not necessarily - it depends on the geometry. The equator, on a sphere like the earth, is a straight line on a spherical surface. It has no endpoint.
What shape is a sphere cut in half?
it's a semi-sphere circle is to semi-circle as sphere is to semi-sphere
How do you find the radius of a sphere?
You have to cut the sphere in half and then measure across.

What is spherical geometry?
It is the geometry of a sphere as well as of shapes on the surface of the sphere.
Could triangles have right angles?
Yes, although a triangle (in normal geometry) can only have one right angle, no more. It is possible for a triangle to have all three right angles in spherical geometry (if you were to draw the triangle on a sphere).
What is elliptical geometry?
It's pretty much geometry on a sphere
What is a sphere or ball called?
Sphere is the term used in geometry.
Is there geometry in basketball?
yes, the ball is a sphere with a diameter and a radius-which is geometry
What is the GEOMETRY name for a ball?
sphere
Is there such thing as a triangle that's angles that don't up to 180?
Yes... and no.Triangles in Euclidian space, or a Euclidian plane - the kind usually considered in school - always add up to 180 degrees.However, other kinds of geometry have been invented, for example, triangles on a sphere. The "lines" that make up those "triangles" are the major circles - the sides of the triangles are thus the shortest distance between those points (along the surface of the sphere). It is interesting to note that the angle excess - the amount above 180 degrees - of such a triangle is directly proportional to the triangle's area.
