What is a flat area on s curved surface called?
A plane horizontal surface with no depth refers to a flat area on a curved surface.
When a curved surface is tangent to a plane surface?
When the two surfaces touch but do not intersect one another.
Explain why the shape of a football is not a polygon?
It has a curved surface.
What is a straight line or plane that touches a curve or curved surface at one point?
A tangent
What is a shape with 1 circular base and 1 curved surface?
A sphere sliced by a plane, eg a hemisphere.
What is a curved surface?
A surface having no equivalent point at any plane
What is a flat area on s curved surface called?
A plane horizontal surface with no depth refers to a flat area on a curved surface.
What is curved mirror?
It is a mirror whose reflecting surface is curved, not flat (as in a plane mirror).
What curved surface compares to which undefined term in Euclidean geometry?
a plane
How many plane surfaces are there in a ball?
None. There is one curved suface but no plane surface.
Difference in plane and curved mirrors?
Plane mirrors have a flat reflecting surface, while curved mirrors have a reflecting surface that is curved either inward (concave) or outward (convex). Curved mirrors can focus or diverge light rays depending on their shape, resulting in different optical properties compared to plane mirrors. Additionally, curved mirrors have a focal point and focal length, which plane mirrors do not possess.
When a curved surface is tangent to a plane surface?
When the two surfaces touch but do not intersect one another.
Is it possible to have a triangle with 2 right angles?
Yes, but not on a plane surface; only on a curved surface.
Explain why the shape of a football is not a polygon?
It has a curved surface.
What is a curve mirror?
It is a mirror whose reflecting surface is curved, not flat (as in a plane mirror).
How many different shapes of mirror surface are there?
Four. Plane, Concave, Convex, and Curved
What is a straight line or plane that touches a curve or curved surface at one point?
A tangent
